Taylor Swift Tries, Fails to Beat Box in Grammys Ad

Taylor Swift rules the world of pop music and country music.

But she might want to leave the rapping up to the host of the 2012 Grammy Awards.

In a great new commercial for that February 12 ceremony, Swift stands alongside LL Cool J and tries to beat box along with the NCIS: Los Angeles star - but quickly realizes she's in way over her cute blonde head. Still, Taylor should not lose all hope: she does a pretty mean Eminem, after all.
