Taylor Swift and Ed Sheeran's highly anticipated duet 'Everything Has Changed' has been leaked online.
The new single, taken from Taylor's Red album, sees the two team up for a mid-tempo balled.
Speaking on the song, the 22-year-old country singer revealed it's inspired by falling in love: "It's about falling in love and the feeling of when you first meet someone and all of a sudden the way that the world looks to you changes." the star told Digital Spy.
The duo penned the love song in Taylor's back garden after they were introduced to one another by their management companies.
Taylor has admitted to being a big fan of Ed and was quoted by The Sun newspaper as saying: "For me Ed is my absolute favourite (British artist), but I've always been obsessed with Florence + the Machine and that sound."
