Swift announced the album on-stage after winning her 13th Grammy award for best pop vocal album for Midnights, which later won her album of the year for a history-making fourth time.

Frenzied fans had been speculating online if the singer-songwriter would announce new music during the ceremony, having made other announcements at previous awards shows.

Picking up the gong, Swift said: "I know that the way the Recording Academy voted is a direct reflection of the passion from the fans."

"So, I want to say thank you to the fans by telling you a secret that I have been keeping from you for the last two years."

"Which is that my brand new album comes out April 19. It’s called the Tortured Poets Department. I’m going to go and post the cover right now back stage. Thank you, I love you."
