Anna Kendrick has been telling Conan O’Brien all about the interesting encounter she had with Katy Perry at the Grammy Awards recently.

Anna claims that Katy “finger-banged” her cleavage, adding that it was a “weird” night – sounds just like our Katy to us!

She did defended the pop star, saying: “I was kind of asking for it. If nobody had done it, I would’ve been a little sad”.

Anna also spoke with Conan about her excitement at meeting her idol Beyoncé.
