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."
