Taylor Swift has announced the first single from new album,The Tortured Poets Department.

The superstar, 34, revealed Fortnight featuring Post Malone will be the debut track from the most hotly anticipated album of the year – set for release on Friday, April 19.

Sharing a snap with Malone, she wrote: ‘The first single from The Tortured Poets Department is…………. Fortnight featuring @postmalone.

‘I’ve been such a huge fan of Post because of the writer he is, his musical experimentation and those melodies he creates that just stick in your head forever.

‘I got to witness that magic come to life firsthand when we worked together on Fortnight.

The star had teased a 2pm announcement on her website before dropping the single release,

This comes after fans have been sent into meltdown over claims that her highly-anticipated album has been leaked online.

Two days ahead of its official debut, snippets of songs credited to the record were being posted on social media, with some revealing that they had been taken from a zip file containing the entire song list.

DailyMail.com has seen a screenshot from a Swifties group chat in which a file containing the allegedly leaked album has been shared.

Upon hearing these snippets, many have claimed that they are fake and created by artificial intelligence (AI) – however others have been left convinced that the songs offer an early access pass to the official album.

A zip file circulating online featured 17 different songs – the same number of hits that Taylor confirmed would be included on her upcoming record.

DailyMail.com has reached out to Taylor’s representatives for comment.

News of the so-called leak sent shockwaves through the singer’s fanbase, with some rushing to listen to the songs, while others were quick to defend the popstar, urging others to ‘report’ any posts circulating the clips and insisting that Taylor’s most die-hard supporters would wait until the official album is released.

‘Tip: Turn Your Device’s Volume COMPLETELY OFF on Twitter for the NEXT 24 HRS and REPORT EVERY POST spamming about album leaks! We got this!’ one person wrote.

Another chimed in: ‘It’s not a Taylor Swift album release if you don’t have fake a** “Swifties” spreading leaks because they can’t wait one day to listen to the project… pathetic.’

A third wrote: ‘Please do not spread the leak of Taylor Swift’s new album. Remember, this is Taylor’s work, respect it, just like you would you favorite artist. Don’t punish the artist for how their fans behave.’

As revealed by Taylor in February, The Tortured Poets Department will featured several collaborations with top artists, including Post Malone and Florence + the Machine.

The Anti-Hero singer announced the latest album at the Grammy Awards earlier that month and now she has shared the track listing for the record, which includes collaborations with the 28-year-old rapper and the Hunger hitmaker.
