Your favorite child and tween stars have grown up quite a bit since you've last seen them. Many have forgone their family-friendly personas in favor of sizzling new looks and careers. Click through to see these 21st century child stars all grown up and hot.

Few child stars have gone through quite the transformation that Miley Cyrus has. Back then, she was Hannah Montana. These days, she's a superstar performer known for her wild antics and style switch-ups.

The child star-turned-pop phenom has changed drastically since Hannah Montana. She married Australian actor Liam Hemsworth, starred in an episode of sci-fi thriller series Black Mirror and released several albums under her own name, including: Bangerz (2013), Miley Cyrus & Her Dead Petz (2015), Younger Now (2017), and She Is Miley Cyrus (2019).

While she still portrays Alex Dunphy on the long-running sitcom, Winter also voiced Sofia in the animated series Sofia the First and starred alongside Burt Reynolds in the movie Dog Years. Modern Family is still a big show, but Winter's outspoken social media presence has gotten her more attention of late.

First you fell in love with them as Julian, aka "Frankenstein," in Big Daddy with Adam Sandler. Then they took on Disney sitcom life, bringing us The Suite Life of Zack and Cody and various spin-off shows and movies. But what are the twins up to now?

The Sprouse brothers made a ton of money in the early 2000s and then took a break to attend New York University. Since graduating, Cole is steaming up the screen as Jughead on The CW's Riverdale and Dylan is dating Victoria's Secret model Barbara Palvin, as well as doing some modeling of his own.

School of Rock. Drake & Josh. iCarly. From age 3, Miranda Cosgrove was a star. In 2010, she added singing to her resume with the release of her album, Sparks Fly.

Miranda Cosgrove continues to act, lending her voice to the Despicable Me movies and starring in the film The Intruders. Her most recent film, 3022, is in post-production.

Miranda Cosgrove's Drake & Josh co-star Drake Bell rose to fame because of the show. Like many stars of his time, Drake's ability to act and sing kept him on screen for several years. But it's a new day. Where is Drake Bell?

Drake's voice is still a lucrative meal ticket for the star. He showed up in the NBC show Smash, and voices Peter Parker, aka Spider-Man, in the Ultimate Spider-Man TV series. He also appeared in MTV's reality show The Challenge: Champs vs. Stars.

We couldn't mention Drake Bell without also checking in on his Drake & Josh co-star, Josh Peck. Josh kept plenty busy after Drake & Josh wrapped...

Josh voiced Eddie in an Ice Age film, a short, and a video game. He also appeared on The Mindy Project with Mindy Kaling, and showed up on one of the biggest shows on TV, The Big Bang Theory. He also co-starred opposite John Stamos on Fox's short-lived sitcom Grandfathered and had a roll on Fuller House. He married Paige O'Brien in 2017, but neglected to send his former co-star a wedding invite.

Just like Ariel Winter, Brodie-Sangster lent his voice to the show Phineas and Ferb, giving life to Ferb Fletcher. He continues to act in movies, with his most recent big role being Newt in the Maze Runner film series.

They were the bro trio that stole the hearts of tweens around the world. No, we're not talking about Hanson, we're talking about the Jonas Brothers! Kevin, Nick and Joe blew up after their appearances in Disney's Camp Rock, but it didn't stop there for the brothers Jonas.

The Jonas Brothers grew progressively hotter, if you can imagine that. After lots of television shows and appearances, Nick and Joe both pursued solo singing careers. Joe's group DNCE had a huge hit with "Cake by the Ocean," while Nick's hit "Jealous" was on everyone's lips in late 2014. However, the siblings realized they are better together and the Jonas Brothers officially went back to making music as a trio. The band released Happiness Begins in 2019.

All three brothers are now married (cue the crying fan girls). Kevin wed Danielle Deleasa in 2009, Joe wed actress Sophie Turner in 2019, and Nick married actress Priyanka Chopra in 2018.

He was the cute little werewolf cub turned howling hottie in the Twilight series. Then it was movie after movie for this hot actor. But now that things have cooled off a bit, it's time to catch up with Mr. Lautner.

The latest from Taylor is that he starred as Dr. Cassidy Cascade on Scream Queens. He also stars alongside Andy Samberg in the BBC/Netflix comedy, Cuckoo.

You know him. You love him. Here's hoping you've upgraded the High School Musical poster hanging in your room for something more recent. But if not, no judgment! Zac Efron has always been a cutie, and the years have only improved his career and his muscle definition.

Has Zac Efron stopped working even for a second? He showed off his acting chops in such films as Charlie St. Cloud and showed off... other things in movies like Baywatch and Neighbors (both the original and the sequel). He most recently starred in Extremely Wicked, Shockingly Evil and Vile as notorious serial killer Ted Bundy.

Vanessa Hudgens, Zac Efron's High School Musical (and onetime real-life) love interest, stayed in the news along with her co-star as they traveled the world together. But when the couple split, Vanessa's career went in its own direction.

After starring in the weird but visually stimulating film Sucker Punch with Abby Cornish and Jon Hamm, Vanessa kept the fire going, appearing in the sexy action films Spring Breakers and Machete Kills. She got to break out her singing skills on Grease: Live, Rent: Live and stars in the 2018 rom-com Dog Days as well as the Netflix holiday movie The Princess Switch.

Guess who else was in Spring Breakers? Child star-turned-super-sweet hottie Selena Gomez! Starting on Barney and Friends, then starring on The Wizards of Waverly Place, Selena Gomez became a mainstay within the who's who of child stars in the mid-2000s.

These days, Selena Gomez is still balancing television and music. She's an executive producer on the compelling Netflix show 13 Reasons Why, and sings the song "Back to You" on the soundtrack for the show's second season. In 2019, she played "Zoe" in The Dead Don't Die. The former Disney star was also once the most followed person on Instagram, but has since taken a hiatus from the popular social media platform, posting only occasionally.

Demi Lovato and child-star buddy Selena Gomez have a lot in common when it comes to their careers. They both got their big start on Barney and Friends and then moved on to star on Disney Channel series. Both later put acting aside to seriously pursue singing careers.

Demi's album Tell Me You Love Me was released in 2017 and, in March 2018, she performed a duet with Christina Aguilera at the Billboard Music Awards. Later the same year, Lovato suffered an apparent overdose which led to her re-entering rehab and canceling the remainder of her tour. "I've always been transparent about my journey with addiction," she said on Instagram. "I now need to heal and focus on my sobriety and road to recovery." In 2019 Lovato signed with Justin Bieber's manager Scooter Braun.

Yet another Barney and Friends alum, Kyla Pratt's resumé is stuffed with gems like Love & Basketball and every Eddie Murphy-led Doctor Dolittle movie. She rose to serious fame thanks to the darling cartoon show The Proud Family.

Kyla Pratt starred as Crystal on the TV series Let's Stay Together as well as Freeform's Recovery Road. She's now a mother of two daughters.

As everyone's favorite annoying little brother on Even Stevens, Shia LaBeouf's career started off positively. Holes really solidified him as a true actor and it seemed like nothing could go wrong for the star. But then...

Though he blew us away in Transformers and Disturbia, news on Shia LaBeouf lately has been less about his roles and more about his antics, from allegedly plagiarizing an art exhibit and then hosting a bizarre pop-up to "apologize" for doing so, producing strange motivational videos, making creepy appearances in music videos and getting arrested. In 2018, the actor announced a biopic based on his own life called Honey Boy. LaBeouf co-wrote the project under the pseudonym Otis Lort. In 2019 LaBeouf will star in Rothchild.

Even Stevens star Christy Carlson Romano put up with little brother Lou (Shia LaBeouf) as Ren. She went on to voice Kim in Kim Possible. Then she sort of faded into Hollywood oblivion.

Christy Carlson Romano has appeared in several shorts, TV movies and indie projects. As far as her personal life goes, she married producer Brendon Rooney in 2013.

After booking a handful of small parts on television, Dakota Fanning had her big break alongside Sean Penn in the drama I Am Sam.

Fanning has been acting nonstop since then, with a film role almost every year since 2001. She will play Squeaky Fromme in the highly anticipated 2019 film, Once Upon a Time...in Hollywood.

Hermione Granger: All the witches wanted to be her and all the wizards wanted to date her. Emma Watson's career has yet to suffer a lull. After the last Harry Potter film was released, she started work on The Perks of Being a Wallflower and a variety of other projects.

In 2017, Emma Watson brought Disney's Beauty and the Beast to life as Belle. Emma is a proud feminist and has become an international spokesperson for women's rights. And not just as a hobby. She has an official station as the UN Women's Goodwill Ambassador. Watson will play "Meg March" in the 2019 film adaptation of Little Women.

Rupert Grint brought us the lovable Ron Weasley, the one who got Hermione Granger in the end. After his time at Hogwarts ended, Rupert starred in a number of indie films including Cherrybomb and Wild Target.

Rupert made his Broadway debut in Terrence McNally's It's Only A Play, which also starred Matthew Broderick. He also stars on the shows Sick Note and Snatch.

We can't forget about Harry! After Harry Potter, Daniel Radcliffe had all the opportunities he could handle. He appeared in The Woman in Black and bared his soul (among other things) on stage in Equus. His career has kept moving full steam ahead, and the future looks even more exciting.

Daniel Radcliffe most recently starred as a flatulent reanimated corpse in the very, very odd indie film Swiss Army Man that earned incredibly positive reviews from critics. Radcliffe is slated for a role in the upcoming untitled Unbreakable Kimmy Schmidt special.

No one could have ever guessed that the perma-awkward Neville Longbottom in the Harry Potter movies would turn out to be a hunk...

...but Matthew Lewis surprised the world when he emerged from his awkward phase as a very hot butterfly. Even though the series has ended, Lewis still acts; he's had recurring roles on Happy Valley and Ripper Street. He married Angela Jones in 2018.

The Suite Life of Zack and Cody and three High School Musical movies made Ashley Tisdale a household name in the early 2000s. She went on to star on the CW show Hellcats.

You may not have seen Ashley Tisdale much lately, but you've definitely heard her. From Family Guy to The Cleveland Show to Phineas and Ferb, her voice is everywhere. On the music side, her third album, Symptoms, was released in 2019.

She brought the Lizzie McGuire to Lizzie McGuire, a show voted a teen fan favorite in 2002 and 2003 (according to Nickelodeon). She released an album called Metamorphosis in 2003 and a self-titled album in 2004. The hits kept coming from Hilary Duff as she starred in A Cinderella Story, The Perfect Man and more.

Hey now, hey now, Duff's career is truly what dreams are made of. The former Disney actress stars on the show Younger and even dipped her toe back into the music world with her 2015 album release Breath In. Breathe Out. Duff was married to hockey player Mike Comrie from 2010-2016 and the two have a son. She is currently engaged to musician Matthew Koma and the two have a daughter.

Raven-Symoné and her dimples entered our living rooms and our hearts thanks to The Cosby Show. She starred opposite Kirsten Storms in Zenon: Girl of the 21st Century before going on to star on her own show, That's So Raven. It turns out that Raven was just getting warmed up.

Raven is here to stay, alright? She appeared on Fox's hit Empire and ABC's black-ish. She has also become famous -- or, perhaps infamous -- for her opinions on socio-political issues. She recently left The View to executive-produce and star in a spin-off of That's So Raven called Raven's Home.

She may have had her big break on Sex and the City as a horrible 13-year-old who hired a publicist for her bat mitzvah, but Kat Dennings really came into the public eye as Maria Piedmont, the teen daughter of Steve Carrell's love interest in The 40-Year-Old Virgin.

For six seasons, Dennings portrayed hard-edged Max on the incredibly popular CBS series 2 Broke Girls. Since that show was canceled, her voice can be heard on The Simpsons and Big Mouth. She has a ton of upcoming projects slated for 2019 and 2020, including: Dollface, Friendsgiving and Croods 2.

Sure, she has a famous auntie in Julia, but it was Emma Roberts' serious acting chops that kept her in movies and shows throughout her childhood. She was Johnny Depp's daughter in Blow and starred on her own show, Unfabulous.

Aside from kicking pledge butt and taking names on Scream Queens until 2016, Roberts has played characters on several seasons of American Horror Story. In 2013 she became engaged to her AHS co-star Evan Peters, but the two called it off in 2019. She is now dating Country Strong star Garrett Hedlund.

Back in 2008, Keke Palmer scored a starring role in True Jackson: VP. One of her first film roles was with Laurence Fishburne and Angela Bassett (Akeelah and the Bee), and her acting career has been on a steady upward trajectory ever since.

Keke Palmer was always a princess in our eyes, but she became a Broadway princess when she brought magic to the stage as Cinderella. Palmer also starred on Fox's Scream Queens, and appeared on the now canceled Star on the same network.

Three words put Abigail Breslin permanently on the Hollywood map: Little Miss Sunshine. How could the world not love her? Since then, she's appeared here and there in shows and movies such as Kit Kittredge: An American Girl, but things are really heating up for this young actress now.

Abigail starred on Scream Queens on Fox along with a number of your other fave child-star chicks, including Emma Roberts and Keke Palmer. She also made an appearance as Baby in ABC's questionable remake of Dirty Dancing. She is slated to reprise her roll as Little Rock in the upcoming Zombieland sequel, Zombieland: Double Tap.

Remember that adorable guy in About A Boy? No, not Hugh Grant, the little one! Nicholas Hoult was super cute back then, but what's he up to now?

Well, Nicholas grew from cutie pie child star to very attractive actor. His breakout starring roles occurred in Warm Bodies and Jack The Giant Slayer. From there, he went on to appear in mega-hits X-Men: Days of Future Past and Mad Max: Fury Road. He welcomed his first child in 2018.

The adorable spawn of Will Smith and Jada Pinkett Smith starred with his father in The Pursuit of Happyness. He also kicked butt with Jackie Chan in the 2010 reboot of The Karate Kid.

Jaden Smith is working on a number of acting and television projects. He also makes music and has released an album titled SYRE in 2017 and another Erys in 2019. He's also a fashion icon, masquerading as Batman at proms and weddings. Smith is also a bit of a visionary, at least on Twitter.

Those who love Arrested Development love Alia Shawkat's portrayal of Maeby Fünke, the incredibly crafty and sarcastic cousin of Michael Cera's George Michael Bluth.

Since Arrested Development'sunceremonious cancellation and intermittent revivals, Shawkat has been a voice on Adventure Time, portrayed various characters on Drunk History, and currently stars on the TBS show Search Party.

In 2000, Jamie Bell starred in Billy Elliot. Watching him in such a moving film, it was hard to imagine that this was Bell's first major role. There was never a doubt that the young actor would go far. So, where did he go?

Jamie Bell is Ben Grimm, aka Thing, in 2015's Fantastic 4. He also starred as Abraham Woodhull on AMC's TURN: Washington's Spies and has a role in the film Rocketman. He's married to actress Kate Mara.

With shaggy hair and bright eyes, Patrick Fugit held his own next to powerhouses such as Billy Crudup, Kate Hudson and Philip Seymour Hoffman in Almost Famous.

Aside from the sleeper favorite Saved, Fugit appeared in acclaimed films We Bought A Zoo and Gone Girl. He is a reoccurring character on the USA Network show Treadstone.

Ellen Page stole our hearts as the accidentally preggers Juno MacGuff in Juno. She's also X-Men's Kitty Pryde. What else is up for this star?

Ellen Page appeared alongside Leonardo DiCaprio and Joseph Gordon Levitt in Inception back in 2010. A few months before the premiere of X-Men: Days of Future Past in 2014, Page announced that she was gay during her speech at the Time to Thrive conference. She's married to dance choreographer Emma Porter. She has starred in many Netflix series including The Umbrella Academy and Tales of the City.

Scott Michael Foster played Cappie, the super-cutie on Greek. Since the show ended in 2011, Foster has appeared on several TV shows. Currently, he's holding down a slick steady gig on a new series.

Since Greek, Scott Michael Foster has appeared on ABC's Once Upon A Time, Blood & Oil and as Nathaniel Plimpton III on the series Crazy Ex-Girlfriend.
