"This is going to be my first and only reaction to the whirlwind news that broke 24 hours ago and that I was swept into," Cotillard began her lengthy post. "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," she said of her longtime partner, Guillaume Canet, and their 5-year-old son, Marcel. "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 judgement, I sincerely wish you a swift recovery," she continued.
"Finally, I do very much wish that Angelina and Brad, both who I deeply respect, will find peace in this very tumultuous moment," she concluded the essay, signing the post: "With all my love, Marion."

The New York Postreported on Tuesday, shortly after news of Brangelina's split, that Jolie had filed for divorce from Pitt after she hired a private eye and learned he was having an affair with Cotillard.
Sources told ET, however, that these reports were simply "not true."
Instead, sources revealed that the split has actually been "a long time coming," as the pair had fought over the past year.

"They haven't slept in the same bed for a big chunk of that," the source said. "When they were in New York City the last time together, they had separate rooms and were on their own schedules."
"Angelina runs a tight ship, and for years, Brad followed her orders," the source further claims. "She always called the shots and he went along with it. In recent months, he hasn't been and has been living his life how he wants to live it."
