Katy Perry dropped her brand new track "Part Of Me" at the Grammy's last night. There seemed to be technical problems all night long with the sound, and they got really bad at one point during Katy's performance. Katy recovered like a star though, and still delivered. I'm looking for the video to her performance, but until then here's her brand new track. Could this be her 7th number 1? I guess we'll see.

And despite what some people are saying I thought her costume was hot.
