Kanye West says he is “deeply ashamed” of his infamous “spazz out” after losing out at the MTV Video Music Awards in 2007.

The Grammy-winning rapper famously threatened to boycott MTV, claiming he had been disrespected after Britney Spears was selected to open the Las Vegas show although Kanye boasted a string of platinum-selling hits that year.

“That was completely immature and disrespectful and non-appreciative of what MTV did for me; MTV made me,” says West, who insists he now regrets his rant. “I should never do anything to disrespect that… I sincerely apologize for that and I’ve grown from that.”

The “Love Lockdown” adds that he is eager to change the public’s perception of him as an arrogant brat, telling MTV News: “I’m embarrassed by some of the things I say. It’s one thing to be confident, it’s another thing to just be completely a spoiled brat. I was really spoiled because my first album got the most nominations ever, I was performing at the Grammys out of the blue… As soon as I hit the game, I hit the ground running; I had respect, I had accolades, I had record sales.”

“It’s time for the honesty to cut through and to grow up and be a man.”
