Kristen Stewart made history today. She is officially the very first American actress to win a Cesar Award. If you aren't aware, the Cesar Awards are France's most prestigious film awards -- kind of like the Oscars in America. Kristen won the award for Best Supporting Actress for her role in the Olivier Assayas directed film Cloud of Sils Maria.

Variety reports that Kristen remarked backstage, "The reasons why people make films here in France are very different from the reasons why people make movies in Hollywood and I prefer it here a little bit." Kristen even began her acceptance speech in French, eventually transitioning back to English.

According to E! News, Kristen's nomination in the Best Supporting Actress category at the Cesar Awards marked the first time in 30 years that an American actress had been nominated, so to take home the award is quite a feat. Kristen was clearly stunned, as she held her hand over her mouth upon hearing her name read.

The movie for which Kristen won, Cloud of Sils Maria, first debuted at the Cannes Film Festival last year and garnered six Cesar Award nominations in total, including best director, best film and one for best actress for Juliette Binoche, who Kristen thanked in her acceptance speech.

Kristen was recently interviewed by Patti Smith for Interview magazine in what turned out to be a very interesting and revealing interview. In it, Kristen defended her decision to star in the Twilight franchise, citing the role as integral to becoming the type of actress she is today.
