It's official: Adele's third album, the follow-up to the world-beating '21', will be released this side of Christmas.

The title of the long-awaited record is still unconfirmed, with reports suggesting that it's called '25', but in any case it will be released on November 20th, according to HITS Daily Double, who say that she has signed an exclusive TV deal with NBC for four big US television appearances across the network's shows to promote it.

The album's lead single is expected to be released in the first or second week of November.

Collaborators on the record have yet to be officially announced, but they are believed to include Tobias Jesso Jr., Ryan Tedder, Danger Mouse and pop producer Max Martin, according to NME.

Blur's Damon Albarn also recently discussed his work with Adele on the album, calling what he'd heard of it 'very middle of the road.'
