Robert Pattinson happy with Kristen, says she understands him

Los Angeles: Actor Robert Pattinson says girlfriend Kristen Stewart is perfect for him because she understands him.

"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," contactmusic.com quoted Pattinson as saying. He also said it was nice to go to the Cannes film festival with her because they could both support each other. "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," he said. The 26-year-old actor has been dating his `Twilight` co-star for around three years. IANS
