Are Brad Pitt and Angelina Jolie headed for a nasty and expensive split?

According to a new report, the two actors, who share six children together, Maddox, 14, Pax, 12, Zahara, 11, Shiloh, 10, and twins Vivienne and Knox, 7, are allegedly preparing to end their marriage less than two years after they wed.

"Brad Pitt and Angelina Jolie are definitely going to divorce soon," Game N Guide reported on Saturday. "According to reports, the split of Jennifer Aniston's former husband and Billy Bob's ex is caused by several marital issues that aroused after years of marriage."

Pitt and Jolie's relationship began on the set of Mr. & Mrs. Smith when Pitt was still married to Jennifer Aniston. Then, in April 2009, just one month after Aniston filed for divorce, Pitt and Jolie went public with their romance during a trip to Kenya.

In recent months, Pitt has faced allegations of infidelity due to his relationship with his Five Seconds of Silence co-star Marion Cotillard, and as the outlet revealed, Pitt has been accused of being "very sweet" with Cotillard on set.

“She must feel like a breath of fresh air to him,” an insider told OK! Magazine in May, via Hollywood Life. “It’s sad because they do still really care about each other. But it’s looking like the only way out of the jealousy and misery is a divorce.”

“For a while, the excitement of getting married masked their troubles,” a Brangelina insider continued to OK! Magazine, according to Hollywood Life, “but lately, they’ve been having explosive fights. Neither of them is sure that they can or should, hang on anymore.”

Jolie “barely eats, she guzzles wine every night and she smokes constantly,” the insider said. And “Brad’s just exhausted from spending so much energy trying to get her to take better care of herself. It’s been hard to watch the woman he loves waste away.”

“Brad was initially attracted to her dark side,” a source told Hollywood Life, “but when [Angie] goes to this dark place she definitely pushes Brad away. It can be really hard on him. He feels he has been more than patient with Angie, but his confidence in their happiness is wearing thin.”
