Katy may have lost out to Grammys big winner Adele in both the categories she was nominated for, but she definitely shined that night thanks to her amazing, angst-ridden performance, which she used to kill two birds with one stone: she got to debut a new song and send a message to her ex, Russell Brand.

KATY PERRY attended the Roc Nation Pre-GRAMMY Brunch on Saturday in a bright pink and aqua dress.

Since there was no prenup between Russell and Katy, the community property law takes effect, which means everything they both earned while they were married will be divided 50/50. And since Katy earned more than Russell did, she stands to lose more.
