The song, Actually Romantic, is about an unnamed fellow popstar - and social media has blown up with speculation that it's a Charli XCX diss track. In a cinema screening to accompany the new album, Swift has now revealed that the track is "a love letter to someone who hates you".

Charli XCX has teased that she’s back in the studio, after inadvertently finding herself in the headlines due to one particular song on the new Taylor Swift album.

"And all of a sudden they start doing too much and they start letting you know that actually, you’ve been living in their head rent-free and you had no idea."
