Lynne Spears’s first foray into publishing is so not a parenting book! I feel deceived.

There were rumors that the tenor of Through the Storm: A Real Story of Fame and Family in a Tabloid World was going to change after news of Jamie Lynn’s pregnancy broke last winter.

But apparently the change was more drastic than anticipated, as it became a page-turning exposé about Britney’s wild behavior as a teen:

In a tell-all book, Spears’ mother, Lynne, reveals her daughter surrendered her chastity to a high school football stud when she was just 14.

Mama Spears, 53, also dishes that the pop icon took a liking to booze when she was a 13-year-old Mouseketeer and began experimenting with drugs at 15.

By age 16, Britney’s wild-child behavior stunned her family when she was caught with cocaine and marijuana on a private jet, Lynn Spears claims.

And there’s more!

Lynne Spears, 53, confesses her regret of losing control of Britney’s career to handlers who promoted her as a sex object and put her in raunchy videos.

She admits she allowed her then 16-year-old daughter to sleep with Timberlake, her Mickey Mouse Club co-star, and went along with the hoax that Britney was a virgin.

Timberlake had shattered the fair-maiden myth in 2003, blabbing to reporters, “She lost her virginity a while ago – and I should know.” He also told Barbara Walters that he gave Britney her first kiss.

Lynne Spears reveals Timberlake was misled and that Britney lost her virginity to a Kentwood, La., high school football player.

Insisting Britney is even more messed up than we originally suspected is probably not the best way to shepherd along that reported reconciliation with her daughter. Haven’t enough people capitalized on the poor girl’s fame?
