So much for this song-and-dance duo.
Sources confirm to E! News exclusively that 22-year-old Pia Toscano and 25-year-old Mark Ballas, who began dating earlier this year, recently called off their romance.
A rep for Pia declined to comment on her relationship, but tells E! News, "She's hard at work on her new album and can't wait for her fans to hear it. Pia is wrapping up her 'American Idol' tour and her album is expected to be released soon."
Ballas is currently gearing up for season 13 of "Dancing With the Stars" with his reality TV partner Kristin Cavallari.
