"I am going to the Grammys and Katy Perry is my date," the Girls star declared.

She went on to express excitement about Perry potentially winning a Grammy, saying: "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."

Williams and Perry apparently met several months ago through the singer's boyfriend John Mayer.
