The normally camera-shy Kristen Stewart recently showed some skin in a sexy topless photoshoot for a Balenciaga Rosabotanica perfume advertisement, Us Weekly reports.

During the shoot, the 23-year-old actress's bare skin was covered in artsy vines and flowers made to look as though they were growing out of her body as promo for the new fragrance Rosabotanica, which she describes as more "lived-in" than Balenciaga's Florabotinca.

"It looks like the vines are starting to grow into her and they're becoming a part of her," Stewart said of her character in the advertisement in a new behind-the-scenes video. "She's clearly very comfortable there and owning it a little bit more."

"It's very much in keeping with the story," she continued, speaking of the brand's second perfume. "In the first one, it was very fresh. It was really clean and very bare in your face. In this, it's a little more lived in. It's like she knows the environment so well that when the lens steps in to take a look at her, it's like, 'I've been here in my world for so long, now who's looking at me?'

And although she detests being photographed by the paparazzi who try and capture her most intimate moments, Stewart said that she didn't mind stripping down for the new shoot, as while filming, she "didn't have to turn into a different person."

"The point was to capture something natural. If you ever feel like you're forcing something or trying to get the shot, suddenly it's just not fun anymore," she said.
