It's a boy for Marion Cotillard and boyfriend Guillaume Canet! The couple welcomed their first son Thursday night in Paris, PEOPLE reports.

The 'Inception' star and French actor-director have reportedly named their new baby boy Marcel.

"Mother and baby are fine," a source said, confirming the birth, adding that the new mom "very happy."

Cotillard announced her pregnancy with Canet in January. The couple, who starred together in the 2003 film 'Love Me If You Dare,' began dating in 2007.

Though Cotillard was spotted wearing a diamond ring on her left hand earlier this year, no engagement news has been revealed.
