Marion Cotillard turns up the heat in the July issue of GQ, and we have to admit, there's a bit of a girl crush going on.

Really, now. Is there anyone chicer or sexier than the French actress? We think not.

Cotillard details the highs and lows of starring opposite Johnny Depp, who plays John Dillinger, in the upcoming film "Public Enemies." (From the sound of it, there weren't any lows...)

And Cotillard takes her craft very seriously: She told the magazine that just two days after accepting an Oscar for her performance in "La Vie En Rose," she headed to a Menominee reservation in Wisconsin to research her role as Dillinger's girlfriend.

Cotillard most recently starred in the latest trend taking the fashion world by storm -- a video counterpart to a traditional print ad.

"The Lady Noire Affair," a cinematic campaign for the "Lady Dior" bag, is completely worth the click to watch her shine in the mini-masterpiece.
