How's R-Patz coping with fame? We ask his co-stars

Fame has not changed Robert Pattinson, says his Twilight co-star Kellan Lutz.

Speaking at the UK premiere of the latest film in the series, Eclipse, Kellan said: ''Rob's in a tough situation, but he is taking it well and fame hasn't changed him.''

Robert became an overnight megastar a couple of years ago when the first of the vampire films was released.

Since then he has not been able to do all the things he used to as Nikki Reed, who plays Rosalie, explained: ''All of a sudden he couldn't walk down the street. Things have changed, now Rob has so many security guards with him,'' she said.

The Twilight Saga: Eclipse has enjoyed a great opening.
