On Sunday afternoon Kristen Stewart caught a flight to Paris, and not only was she rolling solo (where was girlfriend Alicia Cargile?!), but her hair looked like it hadn't been washed in weeks. Yikes! When asked whether she'll marry Alicia, K. Stew kept walking past photographers and declined to comment. Hey, maybe someday!

The 25-year-old actress was headed across the pond to promote her new film American Ultra, which hits theaters next month. She brought her guitar with her, and it seems like the quilited case is a custom Chanel job. Lucky her!

K. Stew covers the latest issue of Marie Claire, and not only does she chat with the mag about her hair being her identity, but she also opens up about her affair with her married Snow White and the Huntsman director Rupert Sanders. You know, the fling that caused Rob Pattinson to dump her? "Speaking very candidly, it was a really traumatic period in my early 20s that kick-started something in me that was a bit more ... feral," she said.

While she wouldn't elaborate further, she did chat about how liberating it was to get rid of her trademark brunette tresses. "My hair was such a crutch. I looked quote unquote 'sexy' no matter what. I could hide behind it," she said. "As soon as I didn't have all that hair, I had to let my face hang out. I felt more confident than I had in a really long time. And it felt really good. Maybe to most people long hair is prettier. But then what? Is your main goal in life to be desired? That is boring as f*ck."

But would it kill her to wash it?
