As Dancing with the Stars goes into its 13th season, the usual reality rejects, professional athletes and general attention-hogging randoms will compete for the crown. The competitors were announced during Monday night's episode of Bachelor Pad, and aside from the noticeable lack of a rumored Jersey Shore jerk, the lineup was pretty predictable. As foretold by the tabloids, Cher's transgendered son, Chaz Bono, will dance with a woman, as will David Arquette. From the reality realm, while Snooki was an interesting theory, she isn't part of the lineup. However, Hills star Kristin Cavallari and non-K Kardashian Rob will join the cast. Rob, like Chaz, has expressed interest in the strict workout and diet regimen the show provides as a means to lose weight. He tells Us Weekly, "You probably wouldn't know, but I'm the most insecure and overweight I've ever been. I'm over 200 pounds, so I want to drop weight and this will be a good start." Pro athletes include women's soccer goalie Hope Solo and LA Lakers baller Ron Artest. Rounding out the cast are randoms JR Martinez, Elisabetta Canalis, Ricki Lake, Chynna Phillips, Carson Kressley, whose Queer Eye will surely make him best dressed, and Nancy Grace...guess that whole thing about Casey Anthony "dancing with the devil" inspired her.
