NSync have confirmed that they know nothing about their new album, with Lance Bass venting on Twitter about Sony's surprise release of greatest hits album The Essential *NSYNC.

The LP features hits and rarities from the boy band and popped up on Amazon this week, with Bass Instagramming a photo of the purchase page and writing: "I love when the record label doesn’t even tell you they are releasing a new ‘NSYNC album tomorrow! Sounds like they don’t anyone to know about it."

Despite its allegedly clandestine release, the album already seems to have sold out, now being listed as 'out of stock'.

"There’s a lot of these songs I don’t think I’ve ever heard, I remember recording them but I’ve never heard them before, so I’m interested in just hearing it,” Bass said on his radio show Dirty Pop.

The tracklisting includes "Believe in Yourself," which they performed on Sesame Street in 2000, and covers of “The Lion Sleeps Tonight” and Boston's "More Than a Feeling".
