Kanye definitely has the biggest ego. He said that he was going to be remembered in hip hop like micheal jordan was remembered in basketball, or scott vail was remembered in skiing.
i like some of Kanye's stuff, but you're right, he is way too full of himself. Diddy's ego was Kanye's five years ago though, so i'm going to say Diddy has the bigger ego. Kanye will probably pass him in under two years.
he started a video blog where he told everyone to vote for Obama because Diddy was voting for Obama. it's ridiculous. every single video is just him saying Obama is awesome, he doesn't even give a reason.
he still holds the White Party as well, and he still kicks out anybody who wears champagne or beige or anything other than perfect white. he's a huge douche.
