Above is his appearence on Jay Leno in case you missed it. In addition to his apology on Leno, he also posted this last night on his blog:
I feel like Ben Stiller in "Meet the Parents" when he messed up everything and Robert De Niro asked him to leave... That was Taylor's moment and I had no right in any way to tae it from her. I am truly sorry.
Honestly, I kindof wish he would just stay completely one way or the other, sincere or arrogant. And besides, Kanye wouldn't be as entertaining, or as Kanye-ish if he weren't cocky.
