Zac Efron and Taylor Swift are out and about promoting their new animated movie The Lorax, and made a stop at the Ellen Show. Turns out, Tay has been teaching Z how to play the guitar, and the two of them performed a number on Ellen. Watch the video below to see what they changed the “Pumped Up Kicks” lyrics to.

Now tell me, darlings… what do you think of Zac’s singing? Also, best comment about his, err, pumped up hair wins! XOXO
