Nobody knows why Lil Mama bum rushed the stage during Jay Z and Alicia Keys' set at The VMAs last night. Well, yes we do. It's because she wouldn't get any attention otherwise and she knows it. But the show must go on right? At first neither Jay nor Alicia acknowledged Lil Stage Crasher, but then Jay took the opportunity to throw shade when he tapped Lil Mama on the leg and told her "You T-Paining right now." Referring to the Hot 97 Summer Jam when he debuted Death of Autotune and T-Pain jumped on the stage unannounced and uninvited.
