Are Brad Pitt and Angelina Jolie headed for divorce?

According to a new report, the former husband of actress Jennifer Aniston may have cheated on his wife with Marion Cotillard.

“There is totally something going on between [Brad and Marion],” an insider told Star magazine, according to a report by Hollywood Life on Wednesday. “They had insane chemistry right from the start, and many crewmembers believe they’ve been acting on it in private.”

Pitt, 52, is currently in England where he and Cotillard are filming Five Seconds of Silence, and apparently, things between them have gotten quite flirty. In addition to building a great working relationship, the two have given one another “affectionate nicknames” and Cotillard reportedly “lights up whenever Brad is around."

“In the past, Brad and Angie have always turned a blind eye to each other’s little flirtations. As long as neither of them took it too far, they thought it actually spiced up their relationship,” the insider explained. “But Brad getting emotionally attached to Marion is totally against the rules. That’s what makes this a unique situation that could threaten their marriage.”

The Star magazine report also claimed the news of Pitt and Cotillard's relationship has so deeply impacted Jolie, 40, that the actress' weight has gotten down to a shocking 79 pounds.

“She’s so frail and gaunt,” the magazine's source revealed, according to 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.”

Pratt infamously fell in love with Jolie on the set of Mr. & Mrs. Smith while he was married to Aniston and after divorcing Aniston, he went on to marry Jolie and the two share six children together, three of who were previously adopted by Jolie.
