It hasn't even been a year and they're dunzo!
Hmm, wonder what happened…
WELL reps have denied comment on the break-up, but Pia Toscano has been super busy with finishing her new album and completing the American Idol tour.
And Mark Ballas? Well he's busy too…on Dancing With The Stars with his partner Kristin Cavallari!
Too much time apart???
