A mentally unhinged Kanye West ruined what should have been a momentous achievement for 19-year-old Taylor Swift tonight at the VMA’s.

Swift had just won the award for Best Female Video when Kanye rushed on stage, grabbed the mic out of her hand and said, “I’ma let you finish, but Beyonce had one of the best videos of all time!” The audience rightfully booed his azz off the stage. You can always expect that fool to cut up at an awards show.

Swift, a country music superstar, has combined album sales of 10 million worldwide and has sold over 20 million song downloads.
