Pia Toscano'American Idol' castoff Pia Toscano has reportedly dumped her long-term boyfriend to go out with 'Dancing With The Stars' pro Mark Ballas.

The New York Post is reporting that Toscano didn't bother breaking up with Carlos Nunez, her boyfriend of four years, before she went on a date with Ballas.

A mutual friend of the couple said, "It seems inevitable to anyone with eyes. They hadn't spoken as often as you'd think once she made the final 12. She kind of played a disappearing act."
