AceShowbiz - Marion Cotillard is reportedly pregnant following Brad Pitt and Angelina Jolie's divorce announcement. The 40-year-old French actress was rumored to be the one who caused Angelina to file for divorce from Brad.

According to X17online, Marion recently revealed in a cover story for Closer magazine that she's with child. The site points out that the actress showed up in a voluminous dress on the red carpet at the Toronto Film Festival last week. Rumor has it, she is due in December.

While Marion did not reveal who's the baby daddy, her cheating rumors with Brad fuel speculation that he's the real father. They began filming "Allied" in London back in March.

According to a source, Angelina was insanely jealous with Brad and Marion's on-screen chemistry. "Angie couldn't handle Brad's sex scenes with Marion," the source reveals, "Her jealousy was out of control. Brad tried for months to reassure her and calm her anxiety, but it simply didn't work. She said her intuition was telling her he was cheating."

The source continues, "Angie has struggled with insecurity over Brad's fidelity for years, but she was never as jealous over a co-star as she was with Marion. She was always paranoid Brad would do to her the same thing he did to Jen."

Brad releases a statement in response to Angelina's divorce filing, saying, "I am very saddened by this, but what matters most now is the wellbeing of our kids. I kindly ask the press to give them the space they deserve during this challenging time."

Angelina's father Jon Voight, meanwhile, tells Inside Edition, "It's very sad. Something very serious must have happened for Angie to make a decision like this. I don't know what it is. It's a sad thing. Say a little prayer. I am concerned for Angie and the children and hopefully I will be seeing them very soon."
