Kristen Stewart has revealed what she thinks is "hot" in another person in a new interview.

The Still Alice star told CR Fashion Book: "For me, the most attractive thing in a person is drive - genuine impulse expressed for the sake of it, not for perception. I think that's hot."

The former Twilight actress, who split from co-star Robert Pattinson in 2013, also said that she trusts her instincts when it comes to forming relationships.

She explained: "It's not hard for me to figure out who I like or who my friends are. I trust my energy meter, but I'm also not afraid to let me people in who might hurt me.

"I do not approach my life tactfully at all. I'm incredibly impulsive and I am definitely an intense weirdo. I love living and I love people. They trip me out and I want to know more about them all the time. That isn't something I can turn off and on."

The actress, who recently became the first American actress to land a César award for her role in Clouds of Sils Maria, also spoke about seeking out challenging acting roles.

She said: "I love putting myself through hell and really experiencing that pain. That’s when I feel the most fulfilled, when at the end I feel like I’ve slaughtered myself. And it’s so worth it."
