Zac Efron and Taylor Swift Duet on “Ellen” (Video)

Taylor Swift and Zac Efron hit up the Ellen show, promoting their new animated film, The Lorax.

The duo, who claim they aren’t dating, pulled out a few guitars so that Zac can show off his new skills. Efron told Ellen that Taylor had been teaching him how to play guitar. “I taught him Pumped up Kicks by Foster the People,” Taylor added.

The two then did their own little “Ellen” spin on the Foster the People smash hit, “really weird, really, weird, All because of Ellen.”

Do you think Zac and Taylor are dating? I love that Ellen is always pushing Taylor about her relationships….They were sitting pretty chummy on the couch.
