It looks like Mark Ballas
and Pia Toscano have had their last dance.
The ballroom pro
and the singer who was shockingly eliminated
from American Idol
have called it quits, a source tells PEOPLE.
Ballas, 25, and Toscano, 22, who started stepping out
in April, agreed to go their separate ways after a heart-to-heart talk this week about their demanding careers.
"They both decided with everything going on that they couldn't give each other what would be fair," says the source. "They mutually decided this."
Ballas is currently rehearsing with Kristin Cavallari
for the next season of Dancing with the Stars
starting Monday, and Toscano is finishing an Idol
concert tour and has an album
The split was first reported by E!
