Twilight star Robert Pattinson may be famous but he says he can still go about his day to day life as normal. ''I hardly ever get overwhelmed, except at big events, mostly I can sneak through town unnoticed'' he said. The actor was speaking at a fan event in London on Wednesday for Twilight sequel New Moon. He was joined by his co-stars Kristen Stewart and Taylor Lautner for the special screening of the second film in the vampire saga. The latest movie is released on November 20.
