Robert Pattinson admits fame can send people "crazy". The Twilight actor has become one of the most famous men in the world since starring in the vampire franchise but says his global super-stardom can take its toll. When asked if he'd lost some of his sanity over the years, the 26-year-old hunk said: "Maybe I didn't even have any sanity to begin with! I feel like that has happened a little bit. I've seen a lot of people dealing with fame and they go crazy quickly and it's frightening." Robert recently forgave his 'Twilight' co-star and long-term girlfriend Kristen Stewart for cheating on him as she is the only person who can understand his life. Kristen had an affair with her 'Snow White and the Huntsman' director Rupert Sanders, and despite initially breaking off their relationship, Robert wanted to give it one more chance as they have a deep connection because they starred in the 'Twilight Saga' franchise together.
