She's a punk rocker!

Wearing plaid and leather, Kristen Stewart touched down in Nice, France on Monday and looked like she was ready to go to a Ramones concert.

Kristen donned a leather motorcycle jacket, plaid pants and old school Adidas shell toes. The Chanel spokeperson was also toting a handbag by the luxury label, which looks a little odd with the menswear ensemble.

The actress is in the South of France for the Cannes Film Festival, where her latest film, Woody Allen's Café Society, directed by Woody Allen, will make its world premiere.

But last week, K-Stew was partying with Miley Cyrus' ex girlfriend Stella Maxwell after the glittering Met Gala. Bye-bye Soko ... Hello, Stella!

Before she landed in France, we caught the surly star wearing her plaid ensemble (sans leather jacket) at LAX. We are kind of digging this look for her -- it's so mid-'90s Gwen Stefani!
