Kristen Stewart is promoting Balenciaga's latest fragrance, Rosabotanica, and the actress goes completely topless on the new ad campaign.

Stewart has been the face of Balenciaga's perfume since early 2012, and became involved with the couture fashion house due to her friendship with former creative director Nicolas Ghesquiere.

Stewart is photographed leaning forward, holding a bottle of the perfume in one hand, level with her flawless face. Her dark hair is swept back, with some stray strands peeking out. The black-and-white ad features the Twilight actress gracing with her signature calm and sultry expression.

A crop of vibrant and lustrous flowers burst from a vine that clings to her bare skin in a highly exotic and sensual image, a concept similar to last summer's campaign for Florabotanica.

Back in 2012, she has expressed that she felt lucky to be a part of Florabotanica. She also said, "there is something natural about it. It's very alive. I think that as a young person wearing it -- considering that I've never worn a scent -- it kind of puts you on this level of, like, 'Whoa, check me out.'"

"On a base level, the reason you want to wear a fragrance is because you want to smell attractive," she added. "That in itself is a pretty mature idea, especially considering the teenager I was. 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 new fragrance contains aromas of hyacinth, fig leaf, grapefruit, pink pepper, cardamom, cedar wood, and patchouli.
