At least he can cry on Dancing with the Stars partner Kristin Cavallari's shoulder.

After about six months of dating, DWTS pro Mark Ballas and American Idol singer Pia Toscano have gone their separate ways, a source confirms to Us Weekly.

The twosome met last spring, when Toscano, 22, performed on an episode of Dancing with the Stars; they began dating in April.

Why are they going their separate ways?

"[Mark's] high school drama was a little too much for Pia," sniffs the source of Ballas, 25, who is set to dance with Hills star Cavallari when DWTS' 13th season premieres next Monday.

When asked about the split, Toscano's rep told Us Weekly: "Pia is focused on the finishing touches for her new album."
