Taylor Swift has dropped a heavy hint that her next single will be Welcome To New York - and that it's going to be released on the web tomorrow.

The 24-year-old country pop superstar took to Twitter to share a couple of snaps of the Big Apple's skyline.

And she captioned them: "Heads up! Something's happening on @itunesmusic at around 11:59pm EST Monday night.. Available worldwide:) #1989"

Inspired by the music of the 1980s, T-Swift's new album 1989 is set for release on 27 October - and is also expected to include current hit Shake It Off.

T-Swift was recently featured in an entertaining new Diet Coke advert with a room full of cats.
