Anna Kendrick has revealed something *really* sad about Pitch Perfect

What is this BS?

Pitch Perfect, the second highest-earning musical of all time (yes, you read that right), didn't only find success with its first movie. The second was even more of a hit, and there's already a third in the works.

Cue: mental images of Fat Amy in that scene.

The Barden Bellas and Trebelmakers clearly did more than just hit the right musical notes, but no one was more surprised by the film's success than Anna Kendrick herself, revealing to Sunday Today that she thought Pitch Perfect was just for nerds!

Woah, back it up, sister.

"When I read the script I was so expecting it to be something I'd seen before. I was just hoping a couple nerds would really like it," she explained.

She was also really weirded out by how popular that 'Cups' song was — "The other people on the charts were Miley Cyrus and Macklemore. They're out promoting and they must be like, ‘What is this bullsh-t?'"

That "bullshit" might just climb back up the charts, thanks to Anna reminding us how damn catchy that tune is. Anyone else already got it stuck in their head? Thanks, AK.
