Jay-Z and Kanye West Perform at MTV VMAs 2011

Jay-Z and Kanye West surprised the audience with a performance of "Otis" at the MTV VMAs in LA tonight. They rocked the crowd with their hit song, though one eager fan tried to get a little too close to the stars and was removed after rushing the stage in the middle of the song. It was a particularly special night for Jay-Z since his wife Beyoncé Knowles announced her pregnancy at the preshow and rubbed her belly after belting out "Love on Top" in a sequin jacket. Kanye also had something to celebrate since he picked up the award for best collaboration with Katy Perry.
