The Dancing With The Stars season 13 pseudo-celebrity cast of 12 new contestants, who will battle on the dance floor for the coveted mirror ball trophy, was officially announced during the “Bachelor Pad 2” on Monday night (August 29). Check cast bios and pictures below.

The celebrity contestants names were leaked a few hours before the official announcement. And as expected there are no big surprises. Actor Ryan O’Neal, whose named was listed in the leak, was replaced by fashion guru Carson Kressley.

Other names like Ron Artest and George Clooney’s ex-girlfriend, Elisabetta Canalis, were more than confirmed after they were caught leaving DWTS rehearsals last week. We cannot wait to see Nancy Grace on the dance floor since she might quickly become this season’s Kate Gosselin.

Who will win Dancing With The Stars 13? My early prediction: Elisabetta Canalis because she is Italian, sexy, hot and wants to conquer the US. The DWTS dark horse: Chaz Bono! The DWTS goofball: David Arquette!

“Dancing With The Stars” season 13 premieres on Monday, September 19, 2011.
