We’ve already heard this rumor, but its gaining new life — thanks to a new book: A new biography by Andrew Morton alleges actress Angelina Jolie had sex with her mother’s boyfriend when she was 16.

Normally, we’d insert a zingy one-liner about Ange being a homewrecker right about here, but at age 16? As they say in the hood, “Where they do that at that?!” Her nauseating May/December romance with Billy Bob Thornton makes a little more sense now…

According to the unauthorized biography, Jolie and her mother, Marcheline Bertrand, could not come to terms with each other after the Tomb Raider star confessed bagging Mom’s BF. Although Angelina, 34, maintains that she shared a close bond with her mum, who died of cancer in January 2007 at the age of 56, Morton snitches claim the pair struggled to rebuild their relationship after Angelina’s betrayal.

“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 tipster once close Angie spilled. “Her mother found out and ended her relationship with the man. 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.”
