Justin Timberlake is set to serve up a double treat for fans by unveiling a sequel to his new album The 20/20 Experience.

The SexyBack singer confirmed the follow-up news during his album release party at Los Angeles' El Rey Theatre on Monday night.

Timberlake addressed speculation his new album is only the first half of a planned project, simply stating, "Those rumours are true," but he declined to give a specific release date.

The announcement comes shortly after acclaimed producer and drummer ?uestlove revealed Timberlake had more material to deliver to fans.

In a post on his website Okayplayer.com, The Roots star wrote, "Spoiler alert. 20/20 Vol 2 comes out in Nov (November). (10 songs now... 10 songs later = 20 vision)... He played me songs out of order and off both records so I (sic) don't know what made the final cut''.

Timberlake turned the release party into a TV special for America's CW network, which will air on Tuesday night - the same day the disc hits US retailers.
