The Rolling In The Deep singer is reportedly planning to drop the long-awaited LP on 20 November 2015.
Music website Hits Daily Double claims to have insider information from a source working on the marketing campaign for the album and alleges that the record will be supported by the release of the lead single early in November.
It is believed the yet-to-be-titled album will be the last Adele will release under XL Recordings/Columbia having reportedly signed a $50m (£32.8m) deal with Sony.
According to the source, the Someone Like You hitmaker is preparing a huge promotional campaign and has signed a deal with NBC to appear on four major US TV shows such as The Today Show, Saturday Night Live, a prime-time special and one other show, possibly The Tonight Show Starring Jimmy Fallon.
