You remember Kanye West's infamous interruption of Taylor Swift during her acceptance speech during the 2009 Video Music Awards. Apparently, he hasn't learned any manners, because on Sunday he did it again.

According to News.com.au,  at Australia's Big Out Festival Kanye was 45 minutes late for his set. He started doing a sound check on the main stage adjacent to Soundgarden, who was in the middle of their performance.

Chris Cornell stopped and announced to the crowd:
