The ‘High School Musical’ hottie and the gorgeous Grammy-award-winning singer performed a duet for Ellen DeGeneres.
Zac Efron, 24, and Taylor Swift, 22, showed off their vocal abilities while paying Ellen DeGeneres a visit.
Zac and Taylor broke out their guitars and serenaded Ellen — how cute is that?
Although there are rumors that the two are dating, Taylor insists that they are just friends. But hey — friends can still sing together, right?
Make sure to watch their interview today, Feb. 21, on Ellen!

i have never fallen in love with a celeb as i have for Zac Efron. i may be madly enough not to let anyone go on a date with him but i realized that Taylor is just as sweet as him so she won’t mistreat him and therefore i realize Zac from my heart and hand him to her and if she refuses, i ask her to return him to me as soon as possible.
Love, Thanks
