Jay-Z VMA Performance Crashed By Lil Mama

Leave it to Lil Mama, whoever that is, to try to close out the already-strange 2009 MTV Video Music Awards with one of the oddest moments of the night.

While it wasn't as ridiculous or rude as Kanye West's meltdown and hijacking of Taylor Swift's speech, the spectacle of Lil Mama climbing on stage for no reason during Jay-Z and Alicia Keys' VMA performance last night was still hilariously weird.

For nearly five minutes, Jay-Z and Alicia Keys were performing “Empire State of Mind,” a number that was to close the always-memorable MTV award show.

But then there was Lil Mama, appearing out of nowhere, standing awkwardly beside Jay and Alicia in a B-girl stance, whatever that is, as the song ended:

What the hell was Lil Mama doing on stage with Jay-Z?

In short, it was a puzzling and random conclusion to the evening.

A representative for Jay-Z, quoted by Entertainment Weekly this morning, says she has “No clue how it happened.” That makes about 10 million of us.

Viewers and celebrities alike had a field day with it. Fabolous even Twittered "lil mama is JayZ’s hypeman, she jus got there late!" That one's pretty good.

It's actually not as remarkable as it sounds, especially following Kanye's drunken antics, but watching Jay-Z’s understated, yet perplexed-seeming body language when he sees her unannounced appearance is still worth watching.
