BRITNEY ATTEMPTS SUICIDE

Terrified she'd lose custody of her sons, an out-of-control Britney Spears tried to kill herself TWICE in the hours after shaving her head, The ENQUIRER has learned exclusively from sources.

Hours after creating a media frenzy by shaving her head, sources say the troubled star tried to take her own life by walking into traffic, only to be rescued at the last second by her staff.

But that wasn't the end of Britney's self-destructive impulses. A short time later she was rushed to a doctor after saying she was going to kill herself and then taking too many Xanax, say the sources.

Britney's emotional collapse was triggered by a "reconciliation" with estranged husband Kevin Federline — that was actually meant to be an intervention, sources tell The ENQUIRER.

And when Kevin warned her that she'd fail a drug test and he'd get custody of their sons, a hysterical Britney went over the edge and ended up shaving herself bald while a crowd of spectators and photographers watched outside Esther's Haircutting Studio in Tarzana, California.

"After she shaved off her hair, Britney had a complete breakdown and tried to kill herself," an insider told The ENQUIRER.
