In an interview with Life & Style, journalist Ian Halperin, who spent 18 months undercover as a photographer to get close to Britney Spears, says she tried twice to kill herself: “The suicide attempts are true. I know all the details about both of them.”

BRITNEY SPEARS’S SUICIDE BOMBSHELL

Britney had such a publicized meltdown that it seemed the world knew every detail. But in his forthcoming book, Halperin exposes her two suicide attempts and much more.

A family insider lends credence to Halperin’s claims, saying that Britney threatened suicide many times during the time Halperin was with her — from November 2006 until last month — especially after the birth of her second son, Jayden James in September 2006.

Halperin also claims he saw Britney using drug use. “I partied with her and was able to really monitor what type of stuff she was using. It’s very concerning.”

And even more dangerous than the drugs, Halperin says, is “how sleazy and destructive” her handlers — from her former, self-proclaimed manager Sam Lutfi to her mother and father — are toward her.
