She's not shy about flashing some flesh! Kristen Stewart showed off plenty of cleavage in a plunging red dress as she stepped out at the premiere of Cosmopolis in Cannes tonight
On the first day of filming On The Road she had to strip off.
And by the looks of things tonight 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 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 paneling which made for an extremely seductive look.
Lady in red: Kristen Stewart donned a stunning plunging red dress to attend the premiere of Cosmopolis in Cannes tonight
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 her beau.
The 26-year-old British star was busy posing up with his co-stars ahead of the screening of the film.
He's my date: Kristen took the red carpet with her On The Road co-star and her boyfriend's best friend Tom Sturridge
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 girlfriend 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.

Snap happy: The British star mingled with female fans on the red carpet and he seemed more than happy to pose for snaps
The film also stars Paul Giamatti, Juliette Binoche, Samantha Morton and She's Out Of My League star Jay Burachel.
Juliette, was instead the lucky lady that got to stay close to Robert on the red carpet as they posed for photographs with writer Don, and director of the film David Cronenberg.
Juliette looked stunning in a strapless black dress that was volumised at the bottom.
Lucky lady: Robert's co-star Juliette stayed close to him all night while Kristen mingled with his best friend Tom
Drawing the line: Robert is said to have refused to go completely naked in the film
Robert is quoted by Metro France as saying: 'Five minutes before we filmed, David told me, "I want to see the bottom of your balls on the top of the frame." At the moment, I reminded myself that I would do anything for him. So I went back to see him and told him that wouldn't happen.
'He took it really well. At the start, it's a very bizarre scene that you won't see again in another movie, I promise.'
However, despite fulfilling his role, Robert also admitted that he thought he wouldn't be good enough for the part, saying: 'I spent two weeks in a hotel room worrying and confusing myself.'
