Tonight Kanye West was in Paris -- worrying about keeping his white sweater white amidst Paris Fashion Week madness -- and in Berlin, where he crashed Drake's Would You Like A Tour? stop at the 0z Arena. Ye popped out of the stage to perform "Black Skinhead" while Drake, in typical Drake fashion, went nuts like a kid on Christmas morning behind him. “I want you to understand…this is my dear friend," Drake said after. "This is the reason I’m standing in front of you today, this is the mentor, this is the God, this is the genius of all geniuses, this is the man that is Kanye mothafucking West.” Aww. Drake's really calling in the big guns for this European leg: Rihanna in Paris, Kanye in Berlin-- who's next? Outkast in Oslo? Beyonce in Brussels?
