Kristen Stewart understands me most: Robert Pattinson

Twilight saga actor Robert Pattinson, who has been dating co-star from the film series-- Kristen Stewart-- for the past three years, says the Hollywood actress understands him the most. ''She understands exactly how I feel. She is an ambitious woman who wants to grow as an actress. She has an excellent radar for what is good and challenges me constantly'' Pattinson said. The actor also enjoyed going to the Cannes Film Festival, where he went to promote Cosmopolis and Kristen for On The Road's screening, with his girlfriend as they had found support in one-another. ''In the end, it was amazing to have each other's support. Her presence at the gala screening of Cosmopolis made me really nervous. She was sitting in front of me. I kept looking at the back of her neck, trying to find out if she was liking the movie or not. I only calmed down when, at the end, Kristen told me she loved it,'' the actor told Elle Brazil.
