Mötley Crüe have been in the studio working on four new songs for the biopic The Dirt, based on the Neil Strauss’ novel The Dirt: Confessions Of The World’s Most Notorious Rock Band.

Bassist Nikki Sixx recently took to Twitter, posting the following: "Fück can I just say it? I’m listening to the roughs of the new Mötley Crüe and it feels real and raw. Everybody is playing like mad and the songs crush. Bob Rock brought the sounds. Plus we have a surprise that will confirm that we’re outta our minds."

In response to a question on how the new songs will fit in, since the film is based on the band's past, Nikki Sixx responds: "You can trust us these are ball busters. Everybody can relax. We're soon gonna smack you upside the head with some killer new tracks. Bob Rock is producing. Its our movie. We know what were doing."
