There are new reports of Brad Pitt possibly cheating on Angelina Jolie with Marion Cotillard. If the rumors are to be believed, what is Cotillard's beau Guillaume Canet thinking right now?

Jolie and Pitt have set the world ablaze with news that they are divorcing. Jolie is the one that filed for divorce, and now there is a report from PageSix that he was engaged in an affair with Cotillard, his Allied co-star.

"[Angelina] hired a private eye because she felt that he was fooling around with her on the set, and it turns out, he was. And that was the final straw," a source told the publication.

While social networking accounts are already buzzing with Jennifer Aniston memes, some are wondering how Canet, who has been romantically involved with Cotillard for nine years, is responding to everything. The French actor has been silent on his social media pages, but as early as last week he and Cotillard were photographed together in public.

There are also other reports via The Mirror that Cotillard is "absolutely devastated" to hear reports of herself being the mistress in Jolie and Pitt's relationship.

"Marion and Guillaume are blissfully happy, and these kind of claims are not what Marion wants to be hearing," a source close to Cotillard's family reportedly said. "She's said that all she wants to do is to enjoy some quality time with Guillaume and their boy." They also added that this PageSix report "doesn't sound like her at all."

Cotillard and Canet have been in a relationship since 2007, though they are not married. They have a son together, Marcel, who was born on May 19, 2011.
