The Twilight star insists that it lets obsessive fans know where he is constantly. He has urged his admirers to keep distance, for he was recently struck by a taxi while trying to escape a group of over-excited devotees on a New York movie shoot.
"I can't remember what my normal life is like," Contactmusic quoted him as saying. “Because of Internet stuff and Twitter, there will be a crowd if you are in a place for more than half an hour... I've learned never to stay in the same place for more than 20 minutes. The biggest challenge is coping with the crowds. I am a quiet, private person. It's strange. You have to change a little bit. Walking down the street comes with screaming," he added.
