Taylor Swift had a special guest performer at her soldout Staples Center show in Los Angeles -- Ellie Goulding! The 'Red' singer teased the audience about their special guest's identity for a while before finally showing off the U.K. crooner.

Ellie Goulding was one of the top acts to see at the 2013 Lollapalooza festival, and it's easy to see why. The U.K. native put on one heck of a show in Chicago's Grant Park!

What do you think of the remix? I am obsessed with it!
