Kristen Stewart reacts after receiving the Best Actress in a Supporting Role award for her role in 'Sils Maria' at the 40th annual Cesar awards

Kristen Stewart reacted with delight as she became the first US actress to receive a Cesar award, the French equivalent of the Oscars.

Stewart was awarded Best Actress in a Second Role for her turn in Olivier Assayas' Clouds of Sils Maria.

The On The Road star performed alongside Juliette Binoche in the film, which follows the story of an actress agreeing to a role in a remake of the play which made her famous.

Meanwhile, Timbuktu won seven of the eight awards it was nominated for.

Stewart also revealed she would be starring in another French film to Variety, but refused to say what it would be.

“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,” she said after winning the award.

Sean Penn was also awarded an honorary Cesar for his oeuvre.
