"Inception" star Marion Cotillard and her boyfriend of three years, Guillaume Canet, are expecting their first baby.

The actress' rep confirmed the news to multiple celebrity websites; the pregnancy was first reported by Us Weekly.

People reports that the baby is expected this spring. Despite being photographed wearing a sparkling ring, a gift from her beau, a source said the couple are not engaged. "They haven't disclosed any plans concerning marriage," the source explained.

The Oscar winner and Canet, a French actor and director, met when they starred together in "Love Me if You Dare" in 2003. They began dating in 2007. They most recently worked together on Canet's film "Little White Lies."

In a 2009 interview with The Telegraph, Cotillard made it clear that she wanted to start a family. "You can't work all your life," she explained. "I was thinking, of course, about my life, which is a lucky, lucky, lucky life. I have the choice to take a big break and I have to do that. I want to have babies so I must take some time to have babies."

In the same interview, she recalled some advice "Nine" co-star Daniel Day-Lewis gave her. "Take care of my life," she recalled the actor telling her. " 'Don't work too much.' He's right."

Next up, Cotillard will star in Woody Allen's "Midnight in Paris," alongside Owen Wilson and Rachel McAdams, and Steven Soderbergh's "Contagion." Cotillard might be making the awards-show rounds this season as "Inception" is up for Best Motion Picture - Drama at the Golden Globes and is getting Oscar buzz.
