Zac Efron and Taylor Swift lend their voices to the new animated film "The Lorax" -- in theaters March 2 -- but who knew the young stars would sound pretty good together in song, too?
Zac and Taylor visited "The Ellen DeGeneres Show" Friday, where they performed a version of Foster the People's hit "Pumped Up Kicks." They definitely took some liberties with the lyrics, much to Ellen's delight.

Zac has been moving away from his "High School Musical" past with meatier roles lately, but we think he'd be great in a movie musical. "HSM 4," anyone?
