Katy Perry is not taking her man John Mayer with her to this year's Grammy Awards. She is instead taking HBO star Allison Williams (who I happen to have a crush on).

"I am going to the Grammys and Katy Perry is my date," Williams told Anderson Cooper during his Anderson Live today. "She's the hottest date. She's a friend of mine and she's nominated as she should be. I can't wait to go. Obviously she's awesome. She's the best."
