Marion Cotillard is the latest Hollywood actress to give birth, with a source telling People magazine that the first-time mom delivered a baby boy last Thursday in Paris. She named him Marcel.

"Mother and baby are fine," said the source, who added that Cotillard is "very happy."    Fans will recognize Cotillard as the haunting wife of Leonardo DiCaprio from last summer's smash hit, "Inception." She also has a starring role in next year's highly anticipated film, "The Dark Knight Rises."  

The 35-year-old is a self-described "hippie-at-heart," commenting to Nicole Kidman back in July that she’s “very happy with what’s happening now and how the awareness is spreading. Because 10 years ago my mindset wasn’t really normal for most people. I sounded like a crazy person talking about the environment.”

“Respect the place you live, be aware of the impact that you have on things,” she added. “I was lucky to have this education growing up. I was born in Paris and raised in the suburbs and then lived in the countryside. We had a beautiful house with a huge garden. When I moved to the country, I was really connected to nature and the seasons.”

Last year, Cotillard accompanied Greenpeace on a trip to the Congo to document the destruction of the rain forest — and its impact on the more than 40 million people who rely on the ecosystem for their livelihoods.   

"It’s one of the most ancient forests in the world, and I met all of these amazing people who are trying to fight against the timber industry cutting down the trees there," she said in Interview Magazine. "People were telling me all about their lives and how they are trying to survive in a country where there is so much corruption. I even slept in one of the forest villages. I really connected to the people there — their hopes and despair and struggles. It was an intense and beautiful trip."
