Kanye West: At the 2009 MTV Video Music Awards, rapper Kanye West disrupted an acceptance speech by country-pop sweetheart Taylor Swift. West -- who apparently flipped out after losing at the VMAs, the Grammys, the American Music Awards and more -- complained once again that the wrong person had been awarded a trophy, but this time it was on Beyoncé's behalf. Just as Swift began her acceptance speech for the best female video award, West jumped onstage at Radio City Music Hall. "Taylor, I'm really happy for you, and I'm gonna let you finish, but Beyoncé had one of the best videos of all time," he said, as a shocked Beyoncé looked on and the crowd began to boo West. In an off-the-record comment, President Barack Obama later described West as a "jackass" for his boorish behaviour at the VMA.
