INSIDER: BRAD PITT to shell out $10 million to bury ANGLEINA’s XXX tape and pix FOREVER!

TO shield his kids from bride-to-be Angelina Jolie’s tawdry past, Brad Pitt is ready to shell out a staggering $10 million to make sure raunchy photos and a rumored sex tape she made never see the light of day, according to an in­sider, who says Brad will do WHATEVER it takes to bury all evidence of Angelina’s wild sex-and-drugs escapades.

While a slew of racy photos have already made their way onto the Inter­net, The ENQUIRER has learned exclusively that there may be even MORE photos floating around – including some involving self-mutilation – as well as a possible sex tape.

Brad, 49, fears that if these rumored photos and video were ever made public, it would scar the couple’s six children emotionally and psychologi­cally, a close source revealed.

Brad and Angelina, who have been together since 2004, are parents to Maddox, 11, Pax, 9, Za­hara, 7, Shiloh, 6, and twins Knox and Vivienne, 4.

“Brad’s out to protect the new image that Angelina has tried hard to build – A-list actress, dot­ing mother of six and UN human-rights crusader,” the source con­tinued. “He’ll do whatever it takes to buy these pho­tos and track down the alleged sex tape.”

According to the source, a team of investigators Brad hired to find incriminating evi­dence of Angelina’s past has told him that the 37-year-old actress may have made a sex tape dur­ing a “drug-fueled session” in 1999.

“THE ALLEGED TAPE was made around the same time that a friend snapped kinky photos of a strung-out look­ing Angelina,” the source continued.

Those photos, widely circulated on the Internet, include some in which Angelina placed black tape over her nipples and a dog leash around her neck. In others, she sported a blindfold over her eyes. During that shoot, Angelina’s tattoo-artist friend Friday Jones inked the name of her now  ex-husband, Billy Bob Thornton, on her pubic area.

While those photos are enough to send Brad over the edge, insiders say he’s more concerned about what has NOT been published yet.

In the fall of 1999, Angelina was photographed during what’s been de­scribed as a 14-hour heroin-smoking bender while holed up in Beverly Hills’ L’Ermitage hotel.

“Angie was so whacked out on dope that she doesn’t recall exactly what she did,” divulged an insider. “But she believes that it may have involved ‘cutting,’ as well as racy sex.”

Brad was blindsided in 2010 when author Andrew Morton exposed An­gelina’s drug benders, lesbian flings and celebrity sex romps – including perverted sex games with ex-hus­band Thornton in his shocking biography of the actress. But the source says it was the eye-popping S&M photos and the prospect of a sex tape that worries Brad the most.

“And there’s a lot Angelina wouldn’t mind erasing from her past,” main­tained Morton. “I don’t think she’d appreciate a teenage Maddox surfing the net and asking, ‘Hey mom, why are you tied up with tape all over your breasts?’”

The source says the raunchy photos are now in the hands of a “reputable agency,” but Brad is trying to locate the amateur photographer who shot the pictures, and to discover if there are even more shocking images that were never made public.

 “He’s willing to spend $10 million if he has to,” added the source. “When it comes to Angie and the kids, money is no object.”
