Guess who ‘finger-banged’ Anna Kendrick’s cleavage at the Grammys?

“”

Anna Kendrick had a very interesting set of experiences at the Grammys over the weekend, not the least of which was having her cleavage “finger-banged” by a big pop star as she told Conan last night. So who was the lucky lady? A woman who knows a thing or two about cleavage: Katy Perry.

Anna also told a hilarious story about how she met Beyonce and Jay-Z in a very cute fangirl moment, but the real highlight was her story (and Conan’s reaction to it) of when Katy decided to get “friendly.”
