The former Sabrina, The Teenage Witch star and Ozzy Osbourne's daughter will show off their fancy footwork with 14 other famous hopefuls as they're paired off with professional dancers for the ninth series of the contest, due to kick off in the U.S. on 29 September.
Other stars preparing to hit the dancefloor include Donny Osmond, singers Mya and Macy Gray and pop star Aaron Carter, as well as former model Kathy Ireland, actress Debi Mazar and a handful of athletes, including Ultimate Fighting Championship star Chuck Liddell.
Singer La Toya Jackson was approached to compete on the show but turned down the invitation because she is still grieving the death of her superstar brother Michael.
She told Access Hollywood, "The fact of the matter is, I won't be doing it, simply because of the circumstances that (are) going on at the moment.
"I can't see myself putting myself into there right now, dancing every single day when I'm still trying to find out what exactly happened to my brother. That's the most important thing for me at this very moment."
Teenage Olympic gymnast Shawn Johnson waltzed home with the crown on the last season of the show, narrowly beating French actor Gilles Marini to take the title.
