Voila: C'est Marion Cotillard's baby bump!

On Monday, exactly a week after her rep first confirmed her pregnancy to, the French actress, 35, debuted her growing belly while arriving at LAX airport in Los Angeles.

Sans makeup, the stunning Oscar winner kept it rocker-chick casual in a hat, long shirt, cardigan, leggings and biker boots as she carried her own luggage (and a guitar case!).

It will be the first child for the Inception star and Guillaume Canet, her actor-director beau of three years.

Cotillard, who won an Oscar in 2007 for La Vie en Rose, won't be absent from the big screen as she preps for parenthood: She'll be seen this year in Woody Allen's Midnight in Paris and Steven Soderbergh's Contagion.
