Mark Ballas to Pia: Come to L.A., Meet My Mama!

4/12/2011 9:00 AM PDT
Pia Toscano is coming back to L.A. today for another round with Mark Ballas, and it's already serious enough for Pia to meet the mom.

Our spies say Pia is flying in from New York later in the day and will have several dates with Mark during her stay.  And they've already scheduled an evening where Mark's mother, Shirley, will break bread with the "American Idol" castoff.

TMZ broke the story ... Pia and Mark had a hot date last Friday and sucked some serious face.  Pia was angling to meet Mark for awhile, and slipped Mark her phone number using "Dancing with the Stars" contestant Chris Jericho as a go-between.

Mark, we're told, is "totally into Pia and thinks she's amazing."

As one spy told TMZ, "They're totally smitten."
