Mixed feelings for Twilight stars Robert Pattinson, Kristen Stewart and Taylor Lautner as Breaking Dawn: Part One premieres in London

The stars of the Twilight saga films spoke of their mixed feelings about the fantasy series drawing to an end as they were mobbed by thousands of fans at the premiere of its penultimate instalment.

Robert Pattinson, Kristen Stewart and Taylor Lautner were at east London's Westfield shopping centre last night for the UK premiere of Breaking Dawn: Part One.

In November next year the series' fifth and final film, Breaking Dawn: Part Two, will bring one of the most successful teen film franchises of recent years to its conclusion.

Pattinson has been catapulted to superstardom since taking the lead role of vampire Edward Cullen in 2008.

Asked how he felt about the series coming to an end, the star known to fans as R-Patz said: "I don't know yet. I feel I've got a whole 10 years solid of Twilight stuff because even after, every job I do, people are going to be like 'so, how does this compare with Twilight', so hopefully in a few years I'll be able to have some reflective view of it."

His co-star Stewart, who plays Cullen's love interest Bella Swan in the films, said she felt "funny" about the saga ending.

Decked out in a black Roberto Cavalli halterneck dress with a McQueen belt and blue trainers, the actress said: "I don't feel finished because I'm going to have to talk about it and thankfully I do love thinking about my whole experience.

"It feels funny to know I don't have to go back and finish more scenes. It feels very light. The largest segment of my life I remember as a whole.

"It was a formative experience and the most indulgent experience as an actor. It was essentially four years and it was so full on for so long."

Lautner, who plays werewolf Jacob Black, said the series drawing to a close was "a bummer because we all have so much fun making movies so it's a little strange, it was emotional. It's strange to be done for sure".

The premiere unleashed what has become the customary bout of teenage Twilight mania.

The actors were joined on the red and white carpet by stars such as X Factor judge Tulisa Contostavlos, singer Pixie Lott, TV presenter Holly Willoughby and Formula One champion Jenson Button.

There to see the stars were some 3,000 predominantly female teenage fans who came out on a cold November night in woolly hats, gloves and scarves.

But some girls had braved more than just the early winter chill to get a glimpse of the heartthrobs and heroines.

Yasmine Mohamed, 18, from Ilford, east London, said she was risking the wrath of her mother to be there.

She said: "I have read all the books and finished the whole series in a month.

"My mum doesn't like me spending my money on them, she just called me and told me to come home, but I'm not going to."

And it was not just young girls. Groups of mature R-Patz fanatics such as Julia Gibbs, Pauline Rowe, Kathleen Davidson, Yvette Hardstone and Monique Wray were also present.

The women, whose ages range from 38 to 62, had met on a Pattinson-themed website and decided to come from all over the country and as far afield as Durban, South Africa, to get a peek at the 25-year-old actor.

Ms Rowe, 52, from Cambridge, said: "It's amazing. It's our first premiere and our first time to see Rob in the flesh. It's nice to be with other mature people."

Ms Gibbs, 54, from Surrey, added: "We're still teenagers inside."

David Chiozza, 18, an Italian film studies student living in London, said he had come to see Stewart. "Her indie movies are what I'm really into," he said.
