Perry performed the song "Part of Me," which was apparently a track that didn't make the cut for her "Teenage Dream" album, but will be included on a yet-to-come re-release.

The song was a generic enough breakup anthem about not having one's soul broken by a rotten ex. Apparently, though, some lyrics were rewritten post-breakup, and Perry sang that new version Sunday:
"You can keep the diamond ring
It don't mean nothing anyway
In fact you can keep everything
Yeah, yeah, except for me"
We get Katy's irritation with her ex, but the money part is kind of odd, since the two recently settled their separation agreement financials and Brand will be walking away with none of Perry's estimated $40 million fortune.
I'm on TEAM KATY! I was smiling the entire time she performed. Brand is an idiot! He will never do better than her.
