Anna Kendrick Thinks 'Cups' Success Is 'Odd'

You guys, Anna Kendrick is totally humble. Case in point: As her catchy tune "Cups (Pitch Perfect's When I'm Gone)" continues to blaze up the Billboard charts, she just totally doesn't get why it's happening. And just to illustrate how completely baffled she is (and remind us why she's an Academy Award nominee), Anna posted this reaction video to her Instagram.

Maybe you should turn on the radio and give it another listen, girl. Then you'll understand all the fuss!
