Watch Anna Kendrick and Conan pretend they're in a musical.

Anna Kendrick recently guest-starred on Conan, talking about naked selfies and bursting into spontaneous song with Conan.

"I, you know, listen...naked selfie your life away! Like go do your thing. But clean your room...wouldn't you prefer a naked girl in a clean room to a naked girl in a dirty room? If I were a guy, I would be seeking out the neat freaks and ask them for naked selfies. It bothers me. Because, girl, you went through all the trouble to, like, you know, strike the pose, do the thing...make your bed. That's all!"
