Lynne Spears Reveals Britney's Sex and Drug-Filled Childhood

In her new tell-all book, Through the Storm: A Real Story of Fame and Family in a Tabloid World, Lynne Spears reveals that Britney did not lose her virginity to Justin Timberlake. Instead, the popstar gave up her chastity to a high school football player at the tender age of 14.

Lynne also reveals that Brit began experimenting with alcohol at age 13 and drugs at 15. Lynne even caught her with cocaine and marijuana on a private jet when she was just 16.

The book is set for release Sept. 16.
