Who run the world? Girls!

This weekend, Katy Perry will reportedly be going to the Grammys, but not with boyfriend John Mayer. According to
Life & Style, she's heading out with Girls star Allison Williams, whose boyfriend, Ricky Van Veen, is said to be good friends with John.

“I am going to the Grammys. Katy Perry is my date. She is the hottest date,” Allison told Anderson Cooper. “She’s a friend of mine, and she’s nominated, as she should be, and I can’t wait to go. She’s awesome. She’s the best.”

Life & Style said the two friends rarely left each other's sides in November when they attended the UNICEF Snowflake Ball in NYC. And now they get to have more fun Sunday night at the big show! They just have to make sure they don't even flash any sideboob or CBS will get upset.
