She stars opposite Brad Pitt in the upcoming romantic thriller Allied.
But French actress Marion Cotillard has been in the news less as Pitt's co-star and more the 'other woman' in the actor's high-profile divorce from his wife of two years (and partner since 2004) Angelina Jolie.
As news of 'Brangelina's' separation was disseminated over Tuesday night and Wednesday (20-21 September), reports that Pitt had an affair with Cotillard while working with her on Allied also began to do the rounds.
Since Pitt and Jolie had also met while working on a film (Mr and Mrs Smith), while the former was still married to Jennifer Aniston, the speculation around the Pitt-Cotillard "affair" gained further traction. Some tabloids even claimed that Joli had hired a "private eye who confirmed her suspicions about an affair between her husband and Cotillard".
However, Cotillard took to social media on Wednesday to disabuse the world of any ideas they may have concerning a relationship between her and Pitt.
In an Instagram post written in both English and French, she announced that she and her longtime partner, the French actor-director-screnwriter Guillame Canet were expecting their second child, and that she wished Angelina and Brad "peace in this tumultuous time".
This is going to be my first and only reaction to the whirlwind news that broke 24 hours ago and that I was swept up into. I am not used to commenting on things like this nor taking them seriously but as this situation is spiraling and affecting people I love, I have to speak up. Firstly, many years ago, I met the man of my life, father of our son and of the baby we are expecting. He is my love, my best friend, the only one that I need. Secondly to those who have indicated that I am devastated, I am very well thank you. This crafted conversation isn't distressing. And to all the media and the haters who are quick to pass judgment, I sincerely wish you a swift recovery. Finally, I do very much wish that Angelina and Brad, both whom I deeply respect, will find peace in this very tumultuous moment. With all my love Marion Ceci sera la première et seule réaction que j'aurai concernant la déferlante inouïe qui à commencé il y a de ça 24 heures et à laquelle je suis mêlée malgré moi. Je n'ai pas pour habitude de commenter ni de prendre au sérieux le tas d'absurdités déversées à mon sujet mais la situation prenant une telle tournure et affectant des gens que j'aime, je me dois de m'exprimer. Pour commencer, j'ai rencontré il y a quelques années l'homme de ma vie , le père de notre fils et du bébé que nous attendons aujourd'hui. Il est mon amour, mon meilleur ami et le seul homme dont j'ai besoin. Ensuite, à ceux qui me prétendent dévastée, je vais très bien merci. Ce genre d'inventions aberrantes ne m'affectent en aucun cas. Et pour finir, à la "presse", à tous les haters, trolls et consorts qui ont le jugement si rapide je vous souhaite sincèrement... un prompt rétablissement. Ceci dit et un peu plus sérieusement, je souhaite à Angelina et Brad, deux personnes pour qui j'ai un profond respect, de trouver la paix dans ce moment tumultueux. Avec tout mon amour. Marion
Cotillard and Canet began dating in 2007 and their first child Marcel, was born in 2011.
In Allied, Cotillard and Brad Pitt play assassins on a mission to kill a German official in 1942 Africa. After they fall in love, and get married however, they discover that one of them is a double agent who the other must eliminate.
Comparisons with the plot of Mr and Mrs Smith — in which Jolie and Pitt played married assassins who're given an assignment to kill each other — are bound to arise.
In the meantime, a short film that Cotillard featured in back in 2010 (Forehead Tittaes), that sent out a message against workplace sexism, has been once again trending on social media:
