Dancing with the Stars: Meet the Season 22 Cast

How you know her: She's been an actress in films (Happiness, Black and White) and on TV (guest roles on Spin City and Liv and Maddie), as well as an author and philanthropist, but she may be best known for being married to Donald Trump for six years. They divorced in 1999.

Partner: Tony Dovolani

How you know her: Once a Hollywood "It Girl," Barton appeared in Notting Hill and The Sixth Sense, and then became a household name as a star of The O.C. Despite some rocky personal stuff in the last few years -- including a DUI, and lawsuits over unpaid rent among other things -- she's still been doing endorsements for fashion labels. She also won praise for her turn in an Irish stage production of Steel Magnolias.

Partner: Artem Chigvintsev

How you know him: The Pittsburgh Steeler is known for his fancy footwork, which has helped lead him to a career 38 touchdowns. Not one to shy away from a flashy, blingy outfit either, he's one of three footballers competing this season.

Partner: Sharna Burgess

How you know him: Flutie's extensive football career includes stints in leagues including the NFL, where he played for the New England Patriots, the San Diego Chargers and the Buffalo Bills. He's currently the lead analyst for Notre Dame football on NBC. At age 53, he's a bit more seasoned than the other NFL competitors on Dancing, but he does have rhythm: he's played drums in a band with his brother for a number of years.

Partner: Karina Smirnoff

How you know him: Boyz II Men! While yes, they're known for a good ballad, let's not forget those sweet moves from "Motown Philly" in 1991. At age 42, maybe he's still got it?

Partner: Lindsay Arnold

How you know her: The mixed martial arts fighter competes in the women's Strawweight division of the Ultimate Fighting Championship and has modeled for Nike and Columbia sportswear. Known for her aggressive grappling and striking, she danced hip-hop, ballet and jazz throughout her childhood, so she'll be a force to reckon with for a few reasons.

Partner: Mark Ballas

How you know him:The Denver Broncos linebacker and Super Bowl 50 MVP is known for being one of the league's best players, but also for his often-memorable on-field dances, including a Key & Peele-inspired hip-thrusting stunt in 2015 that resulted in a hefty fine from the league.

Partner: Witney Carson

How you know him: Where to begin? The reporter, news anchor and talk show host is now pretty much a pop culture fixture who's reported on crime, scandals and all manner of salacious, scoop-worthy stories for decades.

Partner: Edyta Sliwinska

How you know her: The actress began her career in a Mrs. Butterworth's commercial, before moving to a stint on Good Times and then appearing as Tootie on the iconic '80s sitcom The Facts of Life.

She's currently on Real Housewives of Atlanta.
