Motley Crue’s former producer has lashed out at rocker Nikki Sixx, calling his explosive new book "stunningly inaccurate".

Tom Werman is far from impressed with the Crue bass player’s bestseller, Heroin Diaries: A Year in the Life of a Shattered Rock Star, and claims Sixx is "totally deluded" in a letter to the New York Times.

And Werman has applauded rock journalist Alan Light’s review of the book, agreeing with his suggestion that Sixx is "bratty and self-destructive".

The revered producer says, "That’s on the money, but having been there and having read the book, I would go with ‘totally deluded’ or perhaps ’stunningly inaccurate.’"

Werman is particularly upset by Sixx’s book claims that the producer did very little work and left the bassist to take charge of recording sessions for hit albums Theatre of Pain and Shout At The Devil.

He adds, "As the producer of three Motley Crue albums over a four-year period, I found Sixx’s allegation that in the recording studio he did ‘all the work’ with Vince Neil’s vocals while I chatted idly on the phone not only humorous but pure fiction.

"If this distortion of reality is the result of Sixx’s past heroin habit, then his diary is truly nothing more than a pipe dream, and the events to which this book refers may simply be the needle-induced fantasies of an attention-starved junkie."
