Taylor Swift and Zac Efron sing for Ellen

The two huge stars Zac Efron and Taylor Swift guested at Ellen DeGeneris show today. They actually passed by to promote their newest film Dr. Seuss' The Lorax.

Aside from promoting their new animated film, Taylor Swift and Zac Efron clarified also their relationship as friends only. Recently they had been involved to a relationship rumors when they were spotted last month sharing a meal.

Zac and Taylor picked up their guitars and performed 'Pumped Up Kicks' by Foster The People as Ellen watched on. The two made a version of theirs changing some lines and words and replacing it  about them (Taylor and Zac), to Ellen and how Ellen intrigues them.

What makes me laugh when I watch and listen to their lyrics is the part where the line says, "every single time I came on this show, it's really weird, really weird, all because of Ellen".

Watch the video below and tell me how is it.
