On the first day of filming On The Road she had to strip off.
And by the looks of things last night Kristen Stewart certainly doesn't have any problem flashing a little too much flesh these days.
The 22-year-old actress stepped out onto the red carpet of her boyfriend Robert Pattinson's Cannes premiere in a dramatic dress with a very plunging neckline.

Kristen had opted for a fiery red hue which certainly made an impact as she arrived at the premiere of Cosmopolis.
But the actress very nearly suffered a wardrobe malfunction as the dress gaped around the neckline extremely nearly showed off her entire breast.

Kristen's dress not only dipped down to her naval but the back also had slashes of lace panelling which made for an extremely seductive look.

She finished off the elegant outfit with bright lips that matched the shade of her frock.
While she was at the event to support her boyfriend Robert, who is the star of the film, she kept her distance from him.
The 26-year-old British star was busy posing up with his co-stars ahead of the screening of the film.

Hair scare: Tom sported his hair piled up on top of his head, which looked very messy
Instead Kristen took to the carpet with her own On The Road co-star Tom Sturridge and the pair were seen looking very friendly sharing a warm hug as photographers snapped away.
Tom, who is currently expecting his first child with fiancée Sienna Miller, is best friend's with Pattinson and so it's no surprise him and Kristen get on so well.
Daring dress: Not only was the gown low cut but the back of the dress had slithers of lace paneling
Working her magic: Despite normally hating the cameras Kristen appeared to enjoy herself posing up on the red carpet
Still Robert must have been wishing he was able to escort his girlfriend into the screening given her sensational appearance.
Cosmopolis, which is based on Don DeLillo's novel of the same name, tells the story of millionaire Eric Parker who is travelling across the New York to get a haircut but his trip goes anything but smoothly.
In the trailer for the film the actor is seen stripping off and enjoying a romp with several women and is seen reliving himself in his limo.
