In 2009 Jay-Z and Alicia Keys were invited to perform their smash hit “Empire State of Mind” at the VMAs. Lil Mama, who was in the crown, decided she didn’t need an invitation to join the performance.  Towards the end of the song Lil Mama just walked right up on stage and stood next to Hov like she belonged there and although he kept his cool about the situation, you can clearly tell that Hov was heated!! Watch the video of her stage crashing after the jump. @Julie1205
