Look at me Now - Justin Bieber and Chris Brown Live

I mean we obviously all know that the song "Look at me Now" off of Chris Brown's new album features Busta Rhymes and Lil Wayne, but at a live performance in Australia.  Justin Bieber had a surprise guest for us all and brought out Chris Brown himself.  They performed "Look at me Now" but instead of having Busta rap his verse, Justin Bieber decided to take it over and let's just say he killed it.  I don't have the Bieber Fever, but wow, I must say I'm very impressed with Beiber's performance.
