Miranda Cosgrove + Cody Simpson + Greyson Chance

Depending on your age, you may recognize Miranda Cosgrove from iCarly or School of Rock. According to her Wikipedia page, she is also the "ambassador" for Neutrogena, so she evidently has a friend in the Obama administration. Tonight she sings from her album, Sparks Fly. Also on board is Greyson Chance, the little kid who shot to fame on YouTube singing Lady Gaga's "Paparazzi," and Disneyite Cody Simpson.
