Marion Cotillard Pictures With Son Marcel Canet LAX, Paris

Marion Cotillard carried her baby son, Marcel Canet, yesterday when they went through security at LAX. The mother-son duo boarded a plane to Paris, where they dealt with luggage this morning and said hi to Lea Michele, who had apparently made the same journey. They're home in France on a special occasion — Marion turns 36 today! Marion was just on the West Coast completing work on Christopher Nolan's The Dark Knight Rises with costars Christian Bale and Anne Hathaway. She also did her part to promote Contagion, which hit theaters in the US earlier this month. The Steven Soderbergh-directed thriller is still hanging out at the top of the box office three weeks after its release, and we'll see how it fares over the next few days against new movies like 50/50, Dream House, and What's Your Number?.
