PICTURES: Twilight: Breaking Dawn Part 2's Kristen Stewart, Robert Pattinson, Taylor Lautner Dazzle At UK Premiere

It was bittersweet for the stars of 'Twilight: Breaking Dawn Part 2' when they stepped out onto the red carpet for the UK premiere of the final instalment in their vampire franchise.

Kristen Stewart, Robert Pattinson and Taylor Lautner delighted fans, many of whom had been waiting since the early hours, by stopping to sign autographs and have their photos taken as they made their way along the carpet in London's Leicester Square.

Robert Pattinson told red carpet host Alex Zane that Twilight had "changed everything about his life" and confided that he might not even still be acting, had he not got the role of vampire heartthrob Edward Cullen five long years ago.

What other stars came out to give the Twilighters a proper send-off? Pictures below...

Of the 6,000 fans who had camped out in the cold Square, he said: "(The reaction) makes me feel very foreign. It's really nice, it's really nice, especially after five years. They have stuck around, they're still camping out, I respect that. It's very, very, very cold and I don't understand what kind of mental disorder you have."

His co-star Stewart remarked that this final outing was pretty special because "every single bit of the story is done".

Hand in hand, just what the Twi-hards wanted to see

She added, "Usually we're at one of these premieres going, I don't know, you can't really feel it because you're not done. You're a little desensitised by it all because you have another one coming up. This time it's a trip, it is weird."

All seemed well between Stewart and Pattinson, seen hand in hand, with the scandals of the summer put behind them, just in time to say goodbye to the roles that have made them global stars with the Twi-hard fanbase.
