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.

Robert Pattinson new face of Dior.. Don't you just love?!!

Robert Pattinson has reportedly signed a multi-million pound deal to be the new face of Christian Dior's men's fragrance.

The Twilight heartthrob, who is currently promoting the hotly-anticipated final film in the vampire saga, will star in a series of ad campaigns for the brand's line, reported E! News.

A source said the 26-year-old actor has signed a three-year deal with the French fashion house, and that it is thought to be worth close to 12 million dollars.

R-Patz follows a host of Hollywood stars who have fronted campaigns for the brand, including fellow Brit Jude Law and Black Swan actress Natalie Portman.

He is also following in the footsteps of his Twilight co-star and real-life girlfriend Kristen Stewart, who is the face of Balenciaga's Florabotanica scent.

The final Twilight movie, Breaking Dawn - Part 2, will be released in November.
