Kanye West says he is “ashamed” of his infamous meltdown 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 when Britney Spears was selected to open the Las Vegas show.

“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.”
