Taylor Swift & Zac Efron Play "Pumped Up Kicks" On Ellen

As if this song hasn't been featured EVERYWHERE enough... here comes Taylor Swift & Zac Efron to cover the popular Foster the People song, this time on the Ellen Show. I have to admit... Zac can actually sing *betterthantaylor*! During the interview, the pair chat about Valentines Day, dismiss rumors that they've been dating, and promote their new animated movie (w/ Danny DeVito!!): The Lorax.

Check out the video of the song below. [MTV]
