Zac Efron and Taylor Swift stopped by The Ellen DeGeneres Show to promote their new movie Dr. Seuss' The Lorax (out March 2) -- and chatted about everything from Zac's new tattoo to their Valentine's Day plans. Then, Taylor brought out two guitars and performed an original duet with Zac to the tune of Foster The People's "Pumped Up Kicks."
Ellen also got down to the nitty-gritty, asking the pair to clear up rumors about whether or not they're dating. "We are not a couple," Taylor said. "He's awesome, but we're not a couple." When Ellen pressed them further about how they spent Valentine's Day, Taylor explained that she had a "Pathetic Single Girls Party" with all her single girlfriends, while Zac revealed that he went to a screening of his new movie, Liberal Arts, and then cooked dinner with a friend.
