Robert Pattinson needs to take a class in learning when stick a cork in it! The British heartthron has blamed social networking site Twitter.com for ruining his life, because it lets obsessive fans know where he is at all times.

“I can’t remember what my normal life is like,” says Pattz, who was recently struck by a taxi while trying to escape a group of overzealous devotees on a New York movie shoot. “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.”

He added, “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.”
