And by funky, we mean pure fun. The Allied star stepped out for Dior's 2016 Guggenheim International Pre-Party at New York City's Museum of Modern Art on Wednesday, dressing up her baby bump in luxe velvet.
For the occasion, Cotillard naturally wore a Dior dress that also featured another fall trend: a gorgeous shade of forest green. She paired the royal-hued smock dress with over-the-knee black patent leather boots and a major pair of silver knot statement earrings, finishing the look with the perfect 'do -- a high top knot.
Manhattan's fashion elite came out in full force for the soiree, with ladies like It girl and author Alexa Chung, DJ Harley Viera-Newton, model Julia Restoin Roitfeld, and blogger Aimee Song all in attendance.
The same night, the 41-year-old actress appeared on The Late Show, where she opened up to host Stephen Colbert about being pregnant with her first child, son Marcel. "I wanted to eat things I didn't like. I was very worried that my kid would be conditioned in this world anyway, but then he could have many choices, even the things I don't like," she said. "So everything I didn't like, I tried to feed myself with to give him more choices. It's absolutely ridiculous, but I did it."
We're not sure if she's got that same mindset the second time around, but we do know she's killing the fashion game while pregnant with baby No. 2. And just like Cotillard, plenty of celebs have been giddily rocking velvet recently. Check out some of our faves in the gallery below.
