THAT'S CRAZY! NEW BOOK OUT CLAIMS ANGELINA JOLIE SLEPT WITH HER MOTHER'S BOYFRIEND WHEN SHE WAS 16!

She may be a bad girl gone good, but it seems Angelina Jolie is never more than a step away from her scandalous past.
In a new tell-all biography, controversial author Andrew Morton claims that Jolie bedded her mother's live-in boyfriend when she was just 16-years-old, reports RadarOnline.com.

The A-list celebrity, who is often dubbed one of the most beautiful women in the world, was said to have been unable to come to terms with her mother, Marcheline Bertrand, after the unspeakable affair.

The two allegedly struggled for years to repair their damaged relationship, reports Britain's Now magazine.

"Marcheline had a live-in boyfriend whom she was very much in love with, but Ange slept with him when she was 16 and barely out of school," an insider told the mag. "Her mother found out and ended her relationship with the man."

The source went on to add, "When Ange admitted the story to her brother James just a few weeks ago, even he turned on her. She has hardly anyone left in life who likes or trusts her."

As fans might remember, Jolie's mother died of cancer in 2007 at the age of 56.

At the time, Jolie was allegedly devastated and photos from that period reveal her looking gaunt and tired.

The author of the unauthorized biography, Andrew Morton, has also penned similarly controversial works about celebrities like Madonna, Tom Cruise and Princess Diana.

Morton's book on Jolie is due out this winter.
