Hilary Duff. Brenda Song. Miley Cyrus. Romeo Miller. If you're a child of the 2000s, then you don't just recognize these names, you know them -- and their TV shows -- very well. Read on for a look at some of the biggest child stars of the decade that brought us the iPhone, Facebook, and The Suite Life of Zack & Cody. We'll get you caught up on what these idols from the Disney Channel, Nick, and more are up to today.

This star made her mark on Disney Channel's Lizzie McGuire. The 2001-2004 series follows Hilary Duff's title character as she and her friends make their way through middle school. 

The planned Lizzie McGuire reboot is on pause, but the Lizzie McGuire cast isn't: In May 2020, Duff and her costars gathered for a virtual reunion: a table read of an old Lizzie McGuire script.

Outside of Lizzie McGuire, Duff has racked up numerous movie and TV credits. Since 2015, she has starred as Kelsey Peters on TV Land's Younger (pictured).  

The son of the Master P, Romeo Miller made a name for himself at age 11 as the hip-hop performer known as Lil' Romeo. In 2003, he became the star of his own Nickelodeon series, Romeo! The show ran for three seasons. 

Along with acting and music, Miller went on to pursue basketball. He played two seasons of college ball with USC. Later, he competed on Dancing With the Stars. In 2019, Miller released the album, Hidden Treasure, which featured contributions from Decarlo and Crystal Tais.

He stopped being billed as Lil' Romeo in the mid-2000s.   

When Miley Cyrus debuted on the Disney Channel show, Hannah Montana, she was just 13. She worked alongside her country superstar dad, Billy Ray Cyrus. The show produced four seasons from 2006-2011, and inspired a theatrical concert movie (Hannah Montana and Miley Cyrus: Best of Both Worlds Concert) and a big-screen tale (Hannah Montana: The Movie). 

The hits didn't stop coming when Cyrus took off the Hannah Montana wig. She's produced more than a half-dozen gold- and platinum-selling non-Hannah hits, including "Malibu" and "Adore You."  

In April 2020, amid the coronavirus pandemic, Cyrus guested virtually on The Tonight Show Starring Jimmy Fallon (pictured). She promoted her Instagram talk show, Bright Sided.  

On the 2001-2004 ABC show, My Wife and Kids, Parker McKenna Posey played the part of Kady, the youngest member of the Kyle family.   

Since 2019, Posey has starred in the BET sports drama, Games People Play. "I could only imagine how weird it must be for the people that have seen me as a child actor to now seeing me as an adult, especially playing this progressive character," she told PopCulture.com in 2019. 

Posey is seen here participating in the 2020 BET Awards Pre-Show, which was held virtually due to the coronavirus pandemic.  

As a child actor in the 2000s, Dylan Sprouse is best known for starring alongside his twin brother, Cole Sprouse, for three seasons on Disney Channel's The Suite Life of Zack and Cody. (Dylan was Zack.) After the 2005-2008 show ended, the brothers moved onto the spin-off, The Suite Life on Deck (2008-2011) and the 2011 TV movie, The Suite Life Movie. 

A graduate of New York University, Dylan Sprouse oversees the Brooklyn-based brewery, All-Wise Meadery, which specializes in mead, or honey wine.

Tyler James Williams' earliest credits include Sesame Street. He became a star via the 2005-2009 UPN-CW sitcom, Everybody Hates Chris, based on the life of comic Chris Rock. Williams played Rock's younger self.  

Williams has continued his acting career over the years with roles in The Walking Dead, the 2019 movie, The Wedding Year, and Dear White People, both the big-screen film and the Netflix series. He was a series regular on CBS' Criminal Minds: Beyond Borders and ABC's Whiskey Cavalier (pictured).  

Raven-Symoné made her first appearance on screen at the age of 4 on The Cosby Show. As a teen in the 2000s, she became a Disney Channel star. In That's So Raven (pictured), she played a fashionable psychic from San Francisco. She also starred in the Cheetah Girls movies. 

After leaving The View, the daytime talk show that she co-hosted from 2015-2016, Symoné returned to the Disney Channel to star in Raven's Home (pictured), a spin-off of That's So Raven. She was unmasked as the Black Widow in Season 2 of Fox's The Masked Singer. 

Josh Peck's first big regular television gig was Nickelodeon's sketch-comedy show, The Amanda Show. Then he went on to star as Josh Nichols on the Nick sitcom, Drake and Josh, which ran from 2004-2007.

Peck has continued to work steadily. He starred in the short-lived Fox sitcom, Grandfathered, opposite John Stamos. 

Seen here at a 2019 event in Los Angeles, Peck is due to lead Turner & Hootch, a Disney+ series based on the 1980s Tom Hanks comedy. 

Though she got her start as a child actor in the 1990s, Kyla Pratt broke big as a teen in the 2000s. She had roles in two beloved shows: the Disney Channel animated series, The Proud Family (2001-2005); and, the UPN sitcom, One on One (2001-2006). She also starred in the Dr. Dolittle franchise. 

Pratt has been in the news recently with Disney's announcement that it was reviving The Proud Family for Disney+. The new show, The Proud Family: Louder and Prouder, is due to feature the show's original voice cast, including Pratt as Penny Proud. 

Pratt is seen here in the 2019 Lifetime holiday movie, No Time Like Christmas. 

Cole Sprouse got his start sharing roles with his twin, Dylan Sprouse, in titles such as Grace Under Fire, Big Daddy, and Friends (as Ross's son, Ben). In the Suite Life franchise, Cole Sprouse made audiences laugh as Cody, the nerdy twin.

Since 2017, Cole Sprouse has played Jughead Jones on the CW's Riverdale. Like his twin Dylan Sprouse, Cole Sprouse is a graduate of New York University. 

Kyle Massey got his big break via Disney Channel's That's So Raven, where he played the younger brother of Raven-Symoné's title character. In 2007, Massey got his own show, the White House-based spin-off, Cory in the House.

Back in the day, Steven Anthony Lawrence was best known for his role as Beans Aranguren, the nosy neighbor kid on the 2000-2003 Disney Channel show, Even Stevens. 

After his time on Even Stevens, Lawrence had roles in Mike Myers' The Cat in the Hat and 2003's Cheaper by the Dozen. He's continued to work in TV and film. In 2020, he appeared in a music video for the band, Dear Blanca.

After loads of TV guest appearances in the 1990s, Drake Bell broke out as a teen star on Amanda Bynes' Nickelodeon sketch show, The Amanda Show (1999-2002). From 2004-2007, Bell played Drake Parker on the step-sibling Nick comedy, Drake and Josh. 

Since his Drake and Josh days, Bell has pursued a music career. In 2015, he reunited with Josh Peck for an episode of Peck's then-Fox sitcom, Grandfathered. The same year, he was arrested on suspicion of driving under the influence, and made transphobic remarks (which he later apologized for) about Caitlyn Jenner.

In the 2000s, Christy Carlson Romano played Shia LaBeouf's practically perfect elder sister in Even Stevens. She also lent her voice to the Disney Channel animated series, Kim Possible, and starred in the 2002 Disney Channel TV-movie, Cadet Kelly. Her career began at age 12 in the Woody Allen film, Everyone Says I Love You.

Angus T. Jones was 9 when he debuted as Jake Harper in 2003 on the CBS comedy, Two and a Half Men. Jones also appeared in the 2005 holiday TV-movie, The Christmas Blessing.

After appearing in a video where he urged Two and a Half Men viewers to "stop filling your heads with filth," Jones was bumped from the show's regular cast just before the start of Season 11. (He would go on to make guest appearances.) In 2016, Jones partnered with Justin Combs, the son of mogul Diddy, and launched an entertainment company called Tonite.  

In 2000, Shia LaBeouf found TV fame as Louis Stevens on Even Stevens, a Disney Channel family comedy that ran for three seasons. He also starred in 2003's Holes, a film about teenagers who get sent to a juvenile-detention facility where they have to dig, well, holes. 

Post-Disney Channel, LeBeouf starred as Sam Witwicky in the first three Transformers movies. He spent a number of years in the news for run-ins with the law. Including two arrests for alleged disorderly conduct. In 2019, he depicted his troubled upbringing in the award-winning film, Honey Boy, which he wrote and starred in.
