Angelina Jolie Slept with Her Mother's Boyfriend?

And she was only 16...

Celebrity biographies may be a bit dodgy when it comes to the facts, but boy do they grab your attention. In the latest tell-all to make waves in Hollywood, celebrity biographer Andrew Morton wants to let you know about Angelina Jolie's private life, including a claim that she once bedded her mother's boyfriend.

According to RadarOnline, the new controversial book details Jolie's rocky relationship with her late mother, Marcheline Bertrand. In a shocking incident, Jolie apparently slept with Bertrand's lover. when she was just 16.

"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," a source told Now magazine. "Her mother found out and ended her relationship with the man."

The source continues, "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."

Sadly, Jolie's mother passed away from cancer in 2007 at the age of 56. Angelina withdrew from the spotlight shorty after in order to mourn.

Morton's new book, in which he takes a deep look into the life of one of Hollywood's biggest stars, is due to hit shelves sometime this winter.
