TROUBLED BRITNEY SPEARS began boozing aged 13, lost her virginity at 14, then started taking drugs at 15, according to a shocking tell-all book by her mum.
Wild child Britney allegedly first hit the bottle after joining Disney’s squeaky-clean Mickey Mouse Club.
Mum LYNNE claims 14-year-old Britney then had sex with an 18-year-old high school footballer soon after she quit the TV show.
And she had her first taste of drugs at 15 when she went to Los Angeles to record her debut album Baby One More Time.
The sensational revelations were leaked last night ahead of publication of Lynne’s memoir, titled Through the Storm.
Lynne, 53, tells how she regrets handing over control of Britney’s career to managers and allowing her daughter to be promoted as a sex object in raunchy videos at such a young age.
She believes Britney’s wild behaviour as a teenage star is the root of her current problems.
Britney, now 26, has twice been admitted to a hospital psychiatric ward this year.
After the Mickey Mouse Club, Britney spent a year at high school in her home town of Kentwood, Louisiana, where she is said to have lost her virginity at the home of her footballer boyfriend.
As Britney later pursued her pop career, Lynne let her 16-year-old daughter sleep with teen sweetheart JUSTIN TIMBERLAKE, despite claiming she was a virgin.
A source said: “Lynne thought Britney was in love and Justin was good for her.”
Lynne’s book reportedly tells of her horror when Britney, still just 16, was caught with cocaine and cannabis on a private jet.
The book, out on September 16, is set to deepen the rift between Britney and Lynne.
They have been estranged since Britney’s marriage to KEVIN FEDERLINE broke down in 2006, sending the star off the rails.
K-Fed, 30, has custody of the couple’s toddler sons, and Britney’s dad has taken legal control of her life while she recovers from her psychiatric problems.
