People magazine reports that the actress, 35, and her partner, actor-director Guillame Canet, 38, welcomed a baby boy into the world on Thursday night. His name: Marcel.

This is the couple’s first child. Cotillard will presumably have a little bit of time to recuperate and spend time with her new son before she has to report to the set of her next project: “The Dark Knight Rises.”

Production of the film officially began yesterday.
