Brad Pitt and Angelina Jolie's marriage is reportedly nearing its end.

For the last several months, the couple has allegedly be faced with a marital crisis due to Pitt's rumored affair with French actress Marion Cotillard, and as Jolie reportedly wastes away, the 52-year-old actor is said to be preparing to file for divorce.

"The resentment has been eating away at Angelina,” an insider told In Touch Weekly in March, according to a report by Hollywood Life. “She’s prone to think that since she was once Brad’s co-star and seduced him away from his wife, the same will happen to her.”

And now that Pitt has been working with Cotillard in London, Jolie's insecurities have reached an all-time high.

Cotillard is "exactly the kind of sultry European actress that Angie has always wanted to be and she’s playing exactly the kind of role Angie’s always wanted to play,” the magazine's source explained. “Adding to the jealousy is the fact that Marion has one thing Angelina hasn’t achieved in her acting career: Oscar for Best Actress.”

“He will be the one to file," the source continued. "He’s fed up with her controlling ways, her obstinateness when it comes to listening to him about her health issues and how she needs to slow down and now her outright jealousy when it comes to other women.”

Pitt has also reportedly grown frustrated with Jolie's inability to stay healthy. As a report earlier this month revealed, Jolie has dwindled down to a mere 79 pounds, and there's nothiing Pitt can do to encourage a healthier lifestyle.

“She’s so frail and gaunt,” a source told Star magazine, via Hollywood Life. “Brad has tried so hard to help her, but he’s exhausted by trying to care for someone who consistently refuses his help. It’s not wonder he’s gravitated toward Marion, who is healthy and happy and vibrant. She’s a breath of fresh air for him.”
