Kristen Stewart posed topless for her second ad campaign with French fashion brand Balenciaga.

Stewart, 23, was photographed without a top on the black-and-white shot that features the On The Road actress with her back facing the camera. Her bare backside is draped with flowers that were enhanced with color for the brand's Florabotanica line.

The Twilight star's face was slightly glamorous with smoky eye shadow, nude lips and her hair is styled with a tousled updo.

It was confirmed in May that Stewart would continue to be the ambassador for the Florabotanica line. There was speculation she would not continue to work with the company after her friend, designer Nicholas Ghesiquiere left the brand in November 2012. The former Creative Director was replaced by Alexander Wang. Stewart professed her adoration for the former head designer when she said after his exit she would "totally run away with him," according to British VOGUE.

Wang, Balenciaga's current head designer, shocked Stewart's fans in September 2012 when he hired his friend Liberty Ross to walk his Spring 2013 runway show during New York Fashion Week. Wang made the bold move two months after Stewart was caught cheating with Ross' husband, Rupert Sanders. Stewart cheated on then boyfriend Robert Pattinson with Sanders, a film director. Stewart was caught kissing and hugging Sanders after they worked together on Snow White & The Huntsman. Ross, the mother of his two children, also appeared in the film and played Stewart's mother.

Balenciaga's Florabotanica won the prestigious Fragrance of the Year Award at the annual Fragrance Foundation Awards on June 12.
