Stephen Colbert Challenges Kanye, Kanye West Responds on Twitter

Forget about rapper vs. rapper, Stephen Colbert wants to take Kanye West down!

Stephen Colbert wants people to begin purchasing his Christmas album that drops today at 5 p.m. Eastern so he can get Kanye outta the top spot on iTunes, but as you can tell, Kanye isn't happy about this challenge.

You know what? I finally must sign up on Twitter now that I know my future baby daddy is on there. I've been resisting that ish forever. Who do you think will win? Me thinks Stephen's got a pretty good shot. People love him. And if Kanye doesn't know who he is, that's shameful.
