Cotillard announced her pregnancy amidst an unfortunate storm of controversy last fall, when she was rumored to be romantically linked to Allied co-star Brad Pitt, following his split from wife Angelina Jolie.

"Many years ago, I met the man of my life, father of our son and of the baby we are expecting," she wrote of Canet on Instagram, simultaneously shutting down the rumor mill and telling the world her happy news. "He is my love, my best friend, the only one that I need."

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'affecte 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

Though Canet spoke out in September to call the rumors "stupid and unfounded," the actress later said that she didn't take the situation personally.

"I never take anything personally when it doesn't concern me," Cotillard cooly told Today show co-anchor Matt Lauer in November. "So, I didn't take it personally because I had nothing to do with those rumors or situation."
