Zac Efron and Taylor Swift Sing a Duet on ‘Ellen,’ Address Dating Rumors [Video]

Zac Efron and Taylor Swift are currently on the talk show circuit to promote their new movie, “The Lorax,” but the co-stars insist that they are not romantically involved.

Swift and Efron appeared on “The Ellen Degeneres Show” today and addressed the dating rumors. Swift said:

“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 out voiceovers on separate coasts we really connected.”

So who is Taylor Swift dating? When asked about her Valentine’s Day plans Swift said that she spent the night with some girlfriends.

“I actually had a pathetic single girls party. It was cool. That’s actually what it was called. I’m not saying that being single is pathetic. We’ve talked about this. I think it’s awesome… I had all my single girlfriends over and we ate junk food and just ate whatever we wanted and danced. We made these little profile cards about why we’re single.”

Efron did go on a romantic date but he didn’t reveal who it was with. It was recently rumored that Efron was dating Lily Collins but “The Lorax” star is keeping mum about his Valentine’s day sweetheart.

After all the romance talk was out of the way Swift and Efron picked up a couple of guitars and sang a little duet.

Here’s the trailer for Efron’s and Swift’s new movie “The Lorax.”
