Britney Spears' mother Lynne Spears does not "tell all" about when her daughter lost her virginity in her upcoming book, according to the book's publisher.

"It's as far from accurate as you can get," a rep for the publisher Thomas Nelson told FOXNews.com, providing this statement from the company's CEO Mike Hyatt:

"The Lynne Spears book is not yet available for sale, and it won’t be until September 16. So despite certain claims that are being reported by the tabloid press and Internet gossip sites, this is not a 'tell all book' nor a parenting book. The so-called 'facts' that they claim Lynne reveals about Britney and her family are a complete fabrication."

On Thursday, the U.K.'s Sun reported that Lynne Spears writes in the book that Britney was "not that innocent" long before Justin Timberlake.

The paper claims that the book says that Spears lost her virginity to a high school football player when she was 14; began drinking when she was a 13-year-old Mouseketeer; began experimenting with drugs at 15; was caught with cocaine and marijuana on a private jet by 16; and was allowed to sleep with Timberlake at 16.

The book, "Through the Storm: A Real Story of Fame and Family in a Tabloid World," is set for release Sept. 16.
