The new cast of Dancing with the Stars was plucked from the headlines of show business and sports.

Chaz Bono, David Arquette and Kristin Cavallari will join legal analyst Nancy Grace and soccer star Hope Solo in pursuit of the mirror ball trophy on Season 13, ABC announced Monday.

The 12-member lineup, revealed live during the Bachelor Pad telecast, also includes George Clooney‘s recent ex Elisabetta Canalis, NBA star Ron Artest, actress Ricki Lake, singer Chynna Phillips, reality star (and brother to Kim) Rob Kardashian, Queer Eye‘s Carson Kressley, and soap star and Iraqi war veteran J.R. Martinez.

“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,” Bono, the show’s first transgender contestant, tells PEOPLE.

Grace says she thought she was dreaming when she got the call to participate on the show.

“I feel like Cinderella that got invited to the ball. I don t know how to dance,” she admits. “I don’t know what I m going to wear, but I know I have been invited!”

Arquette says that when he asked his 7-year-old daughter Coco what she thought of him doing Dancing with the Stars, “She said, ‘Well, my initial thought is no.'”

Laughing, he added, “I talked to her recently after I decided to do it and she said, ‘I’m all right with it.'”

The contestants, whose professional dancer pairings will be announced Wednesday on Good Morning America, will square off on the live Sept. 19 season premiere.
