First Look: Kelly Osbourne, Aaron Carter on Dancing with the Stars

With Shawn Johnson winning the disco ball last season on Dancing with the Stars, keep an eye on this season's young Hollywood contestants: Aaron Carter, 21, and Kelly Osbourne, 24.

Aaron, who famously caused the feud between Lindsay Lohan and Hilary Duff (they both dated him... meow!), is paired with the always amazing Karina Smirnoff. The reality TV star has been dancing onstage since he was a tween -- even doing some of his own choreography. And his brother is a Backstreet Boy, so he's got to have picked up some tips from ole Nick that Donny Osmond and Tom DeLay don't know about.

As for Kelly, although she says she's "not very graceful" and that dancing "terrifies" her, Ozzy and Sharon's sassy kid was called a "resounding success" when she was Mama Morton in Chicago in London's West End. For DWTS, she'll be getting her groove on with Louis van Amstel, who's back for his fifth season. At the very least, expect her to dance circles around spacey Macy Gray!

They're both already logging lots of hours practicing their moves in anticipation of the Sept. 21 premiere.

Do you think one of them will go all the way? Tell me know below.
