Given their obvious musical talents, it was only a matter of time before Zac Efron and Taylor Swift sang a duet.

That’s exactly what Dr. Seuss’ The Lorax costars did on a recent trip to Ellen (airing today), in which they poked fun at the quirky host.

“Every, every time we come on this show,” they sang, “It’s really weird, really weird – all because of Ellen!” they sang, in what appeared to be the same beat as Foster the People’s “Pumped Up Kicks.”

Meanwhile, the costars also revealed what they did on Valentine’s Day. Taylor, who confessed that being single is “awesome,” said she spent the day hanging out and dancing with her friends, while Zac said he attended a screening of his new movie, Liberal Arts, then cooked dinner for “a friend.” Hmm!!

Check out a clip of their duet in our video now, then be sure to check out Ellen when it airs today!
