Shortly after Angelina Jolie awoke last Tuesday morning at the four-bedroom house Brad Pitt owns in a gated community in Beverly Hills, the couple’s British-based lawyers rang with news that prompted the actress to spend the rest of the day in tears.

Lurid claims the 34-year-old allegedly slept with her mother’s boyfriend when she was just 16 had been plastered across the world’s entertainment headlines.

And worse, this is just one of many claims writer Andrew Morton – most famous for his biography of Princess Diana – will make in his unauthorised biography, which will hit US stores in the new year.

If that wasn’t bad enough, Canadian biographer Ian Halperin has penned a shocking book of outrageous allegations about the star, titled Brangelina, which is due in shops in just a matter of weeks.

“Brad is furious but Angelina is absolutely heartbroken,” says a friend close to the couple. “She spent most of the day in tears and Angie called a couple of friends saying she thinks these books may well be the final straw that finishes her and Brad’s relationship.

“Angie’s worried what revelations will be in the books and she’s had to discuss difficult things with Brad over recent days, knowing that even if the books aren’t published, he is going to read everything in the manuscripts their lawyers are going over.

Morton decamped to LA for most of the recent northern hemisphere summer and has talked to Angelina’s former friends from high school, as well as some of her ex-lovers and former employees.

He is set to detail Angelina’s alleged affair with a female rock star, and he will make detailed claims about how Angelina allegedly lured Brad away from Jennifer, using sex as a weapon.

But Morton’s biggest coup is apparently his lengthy interviews with documentary filmmaker Bill Day, who was in a relationship with Angelina’s mum Marcheline Bertrand for 12 years, and posted a bitter tribute online after her death, taking aim at Angelina.

Morton has also spoken to Angelina’s former lesbian lover, Jenny Shimizu, who makes various claims about the actress and her relationship with Brad.

“The book, like his other biographies, is going to be nothing short of explosive,” says an insider…
