Kristin Cavallari among 12 celebs to hit ‘Dancing With the Stars’ floor

No longer engaged to Bears QB Jay Cutler, Kristin Cavallari is rushing into the arms of a dance pro.

The former star of MTV’s “The Hills” will be one of 12 celebs competing this fall on “Dancing With the Stars,” ABC announced Monday.

Also in the running during Season 13:

† Athletes Hope Solo (of the U.S. national soccer team) and Ron Artest (of the Los Angeles Lakers).

† TV talkers Nancy Grace (of HLN) and Ricki Lake.

† Singer Chynna Phillips of Wilson Phillips.

† Rob Kardashian, sister of Kim.

† Actors David Arquette and Elisabetta Canalis (George Clooney’s ex).

† J.R. Martinez, a wounded Iraq vet who’s on “All My Children.”

† Makeover whiz Carson Kressley.

† Chaz Bono, transgendered son of Sonny Bono and Cher.

One surprising omission: Screen star Ryan O’Neal, who had been the subject of recent “DWTS” rumors.
