Robert Pattinson feels guilty 'Twilight' fans camped out for days to see him at the Los Angeles premiere of 'The Twilight Saga: Eclipse'.

The 24-year-old actor - who plays vampire Edward Cullen in the movie series - didn't know how to react when he heard people had been sleeping outside as early as last Saturday (19.06.10) to catch a glimpse of him last night (24.06.10).

Speaking at the premiere, which was held at the Nokia Theatre, Robert said: "They've been camping out. Some of them have been camping out since Saturday, apparently.

"I spiral into this oblivion of guilt whenever they say that because I don't know what to do. All I can do is sign."

The British star admitted he wouldn't be out late to enjoy the fun of the premiere as he had to work today (25.06.10).

He revealed: "I have to work tomorrow (Friday). I have got a 5am start on a film - 'Water For Elephants'."

Discussing the impending end of the movie franchise - only the two-part 'Twilight Saga: Breaking Dawn' is left in the series - Robert said: "I like all the people that I work with and I guess I'm going to miss all the crowds as well."

Robert was not the only major cast member to tread the special black carpet for the event.

Kristen Stewart - who plays Edward's human girlfriend Bella Swan - wore a white dress by Elie Saab, while Taylor Lautner cut a dashing figure in a black suit and tie.

Kristen joked she wasn't enjoying the glitzy event because of the size of her high heels.

She said: "I'm ready to go inside, but only because my feet hurt."

Ashley Greene, Christian Serratos and Nikki Reed were among the other stars in attendance.
