Taylor Swift has dropped out of performing at the Grammy Awards on Sunday (01.26.20).

The 'Lover' hitmaker was never officially confirmed as a performer at the annual music awards ceremony this weekend, but she was reportedly being lined up for a surprise performance, which is no longer taking place.

Sources have told Variety that the 30-year-old singer - who is nominated for three awards at the ceremony - had been tentatively confirmed as the last remaining ''TBA'' artist on the rehearsal schedule, but she has now decided she won't be taking to the stage.

As of the time of writing, Taylor has not commented on the news, and the reason for her reported cancellation has not been confirmed.

It has also been reported that Taylor will no longer appear at the ceremony at all, despite a tentative seating plan which was released earlier this week, and which saw her sat next to K-Pop group BTS, and one row behind Beyoncé and Jay-Z.

Whilst Taylor's attendance remains unconfirmed, Demi Lovato announced earlier this month she will be performing at the ceremony, and recently revealed she'd be using the stage to unveil new track 'Anyone'.

Confirming her appearance, she wrote on Instagram alongside a professional photograph of her sitting on a sofa with the word ''Grammy Performer'' written down the side: ''I told you the next time you'd hear from me I'd be singing #GRAMMYs @recordingacademy @cbstv (sic)''

Other confirmed performers include Lil Nas X, who will be taking to the stage with his 'Old Town Road' collaborators Billy Ray Cyrus and Diplo, as well as BTS, whose lead member RM teamed up with Nas on a remix of the hit track titled 'Seoul Town Road'.

The star-studded bash at The Staples Center in Los Angeles will also see performances from the likes of Ariana Grande, Billie Eilish, Lizzo, Jonas Brothers, Alicia Keys and more.
