This video is hilarious. It features Taylor Swift and Zac Efron on the Ellen Show singing their version of “Pumped Up Kicks” by Foster the People.

The two singers pulled out their guitars and sang the duet and chatted with Ellen about their dating rumors and what they really did for Valentine’s Day.

Taylor stated, “We are not a couple. He’s awesome, we are not a couple though. You hear people get together when they’re shooting movies, co-stars. But not like animated co-stars. You know what I’m saying. Oh my god, as we were recording our voiceovers on separate coasts we really connected.”

Side Note: Taylor is wearing an Oscar de la Renta floral cotton dress.
