Taylor Swift fans should not get their hopes up when it comes to Taylor beatboxing.

She is no bueno.

LL definitely does his thing though, and Taylor does what she does best . . . looks cute in a nerdy sort of way.

LL Cool J lays down the beat for the 22-year-old ‘Speak Now’ hitmaker, but when it’s time for her to pick up on her end, she falls flat and just makes weird nasally noises with her mouth.
