Big night: Robert Pattinson joined his Australian co-star Emilie De Ravin at the London premiere of his new film Remember MeLondon's West End was besieged with hundreds of teenage girls last night as they clambered for a glimpse of their idol Robert Pattinson.
The 23-year-old actor was greeted by screaming fans as he arrived for the Leicester Square premiere of his new film Remember Me.
Some fans had camped out since Tuesday to get a prime position ahead of the star-studded screening.
Mania: Pattinson was greeted by hundreds of screaming fansThe Londoner made sure he rewarded their patience by signing autographs and posing for photos with the hysteric pubescent crowd.
Modest Pattinson, dubbed RPatz by fans, admitted he was still getting used to the fan hysteria, which kicked off in 2008 when he first played vampire Edward Cullen in the first Twilight movie.
He said: 'I never go to places where crowds congregate, so it's always a novelty. It's a completely separate aspect of my life. It's nice.'
Strike a pose: Pattinson poses for a photo with one lucky fanHe said he was grateful the success of Twilight was rubbing off on the low-budget Remember Me.
Pattinson explained: 'The idea that Twilight can help little independent films push through Alice In Wonderland and £100million budgets is nice.'
Predictably nowhere to be seen was his Twilight co-star and real-life girlfriend Kristen Stewart, who avoids making public appearances as a couple with Pattinson.
Instead, he posed for photos on the red carpet with his Australian co-star Emilie De Ravin, who looked cute in a black lacy mini-dress and studded heels

He finds himself drawn to Lost actress De Ravin's Ally - to the chagrin of her protective father Neil (Chris Cooper).
The drama includes some steamy love scenes between Pattinson and De Ravin, including one where they enjoy a clinch in the shower.
Making a colourful entrance at the premiere was reality TV star Bianca Gascoigne, in a floral mini-skirt, bright pink blouse and matching heels, which she combined with a clashing green clutch bag.

Also providing some glamour was Australian singer/actress Holly Valance and model Olivia Inge.
Among the celebrity couples in attendance were Pattinson's Harry Potter co-star Tom Felton with his girlfriend Jade Olivia and tennis star Greg Rusedski and wife Lucy.
• Remember Me is due for release in the UK on April 2.
