Kristen Stewart in Zuhair Murad at Twilight premiere

'Twilight' actress Kristen Stewart dazzled on the red carpet at Leicester Square before having an almighty make-under.

She famously loves being comfortable in trainers (this time last year, at the London premiere of The Twilight Saga: Breaking Dawn: Part 1 , she famously swapped her high heels for black Nikes under her Roberto Cavalli gown when no one was looking) but Kristen Stewart did at least manage to last out the red carpet part of last night's premiere in the highest of heels - and no underwear.

The 22-year-old dazzled in front of thousands of British fans (many of who had camped overnight) at the Leicester Square premiere of The Twilight Saga: Breaking Dawn Part II in a backless, lace jumpsuit by Beirut-based designer Zuhair Murad. 

The heavily embellished couture creation harked back to the cobweb-style Marchesa gown she wore to the premiere of Snow White and the Huntsman back in May, and the aforementioned Cavalli gown, and featured lace panels down the side of the legs, leaving no room whatsoever for any undercrackers.

Meryl Streep for another Devil Wears Prada role, but weight permitting

Meryl Streep confirms she would reprise her role as Miranda Priestley in The Devil Wears Prada 2 - but would have to lose weight first.

So we're very excited to hear that Meryl Streep would reprise her screen-stealing role as the aforementioned 'Devil' and Runway editrix Miranda Priestly, should a silver-screen adaptation be made of Revenge Wears Prada: The Devil Returns - although there is one issue currently standing between Streep and Priestley's sample-size Prada threads.

Speaking to Access Hollywood at Tuesday night's Women in Film Crystal and Lucy Awards - where she was feting fellow Oscar-winning actress and friend Viola Davis - Streep at first stumbled when questioned on the possibility of stepping back into Priestley's perfectly-polished shoes. "Yeah, no. No. Is there one? I've never heard about it," she said, before quickly adding, "But sure. I mean, I'd have to lose the f***ing weight, but yes, I guess I would do that."

So becoming Miranda Priestly once again may involve some serious method eating on Streep's part, but we think it will definitely be worth it.
