Kristin Cavallari and Rob Kardashian are set to battle it out on the new series of Dancing With The Stars.
Ricki Lake, Chaz Bono, George Clooney's ex Elisabetta Canalis and singer Chynna Phillips will also don their dancing shoes for season 13 of the popular program, which kicks off on 19 September (11).
Other stars set to show off their fancy footwork include legal analyst Nancy Grace, NBA athlete Ron Artest, fashion expert Carson Kressley and actor J.R. Martinez.
Cher's daughter Bono, who recently underwent sex change treatment to become a man, tells People.com, "Doing this show is an opportunity for me to reach a larger more mainstream audience with just a simple message of being transgender is okay and not something to be scared of."
Arquette is looking forward to the challenge, but admits his daughter Coco was wary of him signing up.
He adds, "She said, 'Well, my initial thought is no.' I talked to her recently after I decided to do it and she said, 'I'm all right with it.'"
