Kristen Stewart strips off in new Balenciaga perfume ad

Wearing nothing but a sprinkling of flowers, Kristen Stewart puts on rather a racy display in the new campaign for Balenciaga.

Starring in the advertising campaign for the fashion house's new fragrance Florabotanica, Kristen, 23, is pictured from behind, looking over her shoulder with her back covered in colourful flowers. The rest of the shot is in black and white.

The Twilight star's dark hair is pulled into a stylish, loose up-do and her eyes and eyebrows are defined to give her trademark sultry stare.

And is that the tiniest hint of sideboob we see there? Probably about as close as you get in high end fashion commercials...

Kristen, who is friends with the former creative director of Balenciaga, Nicolas Ghesquiere, has been working with the brand since 2012, despite Alexander Wang recently taking on the role from Ghesquiere.

Speaking about the new perfume last year, Kristen told WWD: "There is something natural about it. It’s very alive.

"I was never the one wearing my mom’s perfume and trying to be sexy. I was like hanging out with my brothers and doing the opposite of that."

The shot follows on from the first image of the campaign that began last year. There, we saw a fully-clothed Kristen surrounded by menacing-looking flowers, giving the floral theme an edge.

In a Q&A ahead of the launch, Kristen said: “Luckily, I like the smell of the fragrance so I don’t have to lie about that."

The On the Road star has credited her pal Ghesquiere for reinventing her red carpet style, showing off a more polished, high end fashion look than we'd come to expect from R-Pattz ex. And her continuing relationship with the Parisian design house can only do her image good.
