WATCH: Taylor Swift & Ellie Goulding Duet on "Burn"

Taylor Swift loves inviting guest stars to come out and sing with her while on tour. Last year, Tegan & Sara joined the country star for a duet of their hit, "Closer." Then there are the likes of Carly Simon, Fall Out Boy, Nelly and Train, who have all stopped by.

For the last night of her year-long world tour in support of Red, Swift brought out Ellie Goulding. The two sang a duet of her latest single, "Burn," which has been heating up the charts in the U.S.

However, this was not Goulding's first time singing with Swift. She made an appearance at Swift's L.A. concert where the two took on "Anything Could Happen."
