Mandy released her first album at age 15, but has since gone from pop tart to movie star, with roles in Walk to Remember and American Dreamz. You can catch her over the holiday in License to Wed as she and The Office's John Krasinski take on Robin Williams as a wedding pre-crashing priest. Guess this holy turn is penance for Patch Adams. And Toys. Oh, and RV. OK, pretty much anything that might make a Robin Williams box set.
