Kanye West Interrupts Taylor Swift's Speech at MTV VMA's

Kanye West has officially lost it! While at the 2009 MTV VMA's Kanye rudely interrupted Taylor Swift's acceptance speech for 'Best Female Video' by grabbing the mic from her and acknowledging Beyonce instead.

Beyonce was up against Taylor and lost, which clearly angered Kanye.

Kanye grabbed the mic from Taylor and said, "Yo Taylor, I'm really happy for you , I'm going to let you finish but Beyonce had one of the best videos of all time...one of the best of all time!"

The audience then booed him until MTV cut to a clip. Unbelievable! You would think a 32-year-old man would know better than to insult a 19 year-old girl, but Kanye clearly doesn't.

According to MTV.com, once cameras cut away from the action, West flipped off the crowd and returned to his seat.
