Taylor Swift and Zac Efron are NOT Dating, but They Play Together Nicely on Ellen [VIDEO]

Everybody right now is speculating that Taylor Swift and Zac Efron are dating. And Ellen, being Ellen and a good friend of Taylor's, tried to push them into admitting they were dating. They didn't take the bait, but they did play together very nicely. Guitars that is. They played "Pumped Up Kicks" by Foster The People. Taylor had actually just shown Zac how to play it on guitar, because he doesn't play guitar. So obviously they're both good with their hands. Here's Ellen trying to get them to admit to dating.

And here's the 2 of them jamming on Ellen's couch.
