Kristin Cavallari & Mark Ballas rehearsing for "Dancing With The Stars" at the rehearsal studio in Los Angeles on Sepember 15, 2011.
Looks like there may be some truth to those Mark Ballas and Kristin Cavallari hookup rumors -- because he's officially a free man!
The "Dancing with the Stars" pro and "American Idol" wannabe Pia Toscano have split, this according to People.
The two started dating back in April, while Pia was a contestant on the FOX singing competition.
The split is said to be "mutual."
Spotted: Kristin shopping at Kitson on Sepember 14th.
