Katy Perry is looking blue on the red carpet.
Wearing a cleavage-baring outfit, Katy Perry hit the stage at the 2012 Grammy Award initially belting her hit single, “E.T.” But the tune abruptly stopped, giving way to her brand new hit “Part of Me,” which appears to be about her estranged husband, Russell Brand.

The song is about a romance gone terribly wrong:

“You’re not gonna break my soul. This is the part of me that you’re never gonna ever take away from me, no… I just wanna throw my phone away. Find out who is really there for me ’cause you ripped me off. Your love was cheap, was always tearing at the seams. I fell deep and you let me drown. But that was then and this is now.”

The lyrics continue:

“You can kick the diamond ring. It don’t mean anything anyway.”
