Taylor Swift has teamed up with Ed Sheeran on new track Everything Has Changed.
Ed wrote the song for Taylor's new album Red, which is due out 22 October.
A source told The Sun in June, when they were working together on the track, which has been leaked online: "She's into her British music and became a massive fan of Ed…there is a mutual affection between the pair."
And according to their Twitter accounts at the time, the pair were having a great time together.
Taylor tweeted at the time: "Eating cheeseburgers, scribbling on guitars, writing songs with @edsheeran. : )."
Ed confirmed this moments later with a burger-related tweet: "In and out burger, defacing guitars and writing music with @taylorswift13 : )"
