Marion Cotillard Pictures With Guillaume Canet

Marion Cotillard got fancy in Dior for a dinner last night at Paris's Le Meurice hotel. The evening was organized in support of France's César Awards, their equivalent of the Oscars, and in particular their Most Promising Young Actor category. It was a rare night out for Marion alongside her boyfriend Guillaume Canet, who is the father of her young son Marcel.

Guillaume, who won a César in 2010 for directing Tell No One, will actually host the 2012 ceremony on Feb. 24. He was also crowned Most Promising Young Actor back in 1998. Marion, meanwhile, has two Césars of her own, one for A Very Long Engagement and another for La Vie en Rose, which also earned her an Academy Award.
