DailyMail.com has contacted representatives for Cotillard and Canet for comment but hasn’t yet received a response. 

While Cotillard is well-known for her roles in acclaimed French films, she has also gained recognition as one of France’s top international stars for her performances in prominent English-language movies such as Inception and The Dark Knight Rises directed by Christopher Nolan.

She won the Academy Award for Best Actress for the 2007 biopic La Vie en Rose, in which she portrayed the legendary French singer Édith Piaf. 

In the world of French cinema, Cotillard and Canet were a power couple, with both of them being respected figures in the industry. Canet, in addition to being an actor, is also known for his work as a writer and director.

They announced that they had ended their relationship in a statement to the Agence France-Presse news agency in which they said they were publicly revealing their breakup ‘to avoid all speculation, rumors and risky interpretations.’ 

The former couple didn’t share why they were separating, but they said it was by ‘common accord’ and was with ‘mutual goodwill.’

The two had known been friendly for a decade before then, and they had appeared on screen together in the French-language film Love Me If You Dare from 2003.

Despite having apparently never tied the knot, Cotillard and Canet were forced to deny that they were married multiple times over the years.

Adding to the confusion was the Contagion actress habit of wearing a diamond ring on her left ring finger, which her partner had given her as a present.

However, they clarified that it didn’t signify that they were engaged. 

In 2011, they welcomed their first child, a son named Marcel, and they later welcomed a daughter named Louise in 2017. 

In addition to a long-running romantic relationship, Cotillard and Canet continued a years-long professional collaboration.
