Video: Keri Hilson & Kanye West Perform "Knock You Down"

So, Ghostface Millah and I've popped off about Ms. Hilson in the past -- I go back and forth about how I want more from her. And, I still do, but each day I find myself liking her more and more, mainly because of her personality. While I'm still waiting to hear a track that blows me away, I can honestly say I'm slowly becoming a fan.

Last time we talked about how Keri and Kanye had mad chemistry in the official video for "Knock You Down," but apaprently it also translates in their stage performance from last night's David Letterman without being overt. The performance itself is pretty entertaining, though theatrical at times thanks to all the choreographed dance moves, but it works for me. So, what do you think, take it or leave it?
