Rosie Huntington-Whiteley looks to have transformed into a flasher for a new ad campaign - wearing a mac and nothing else.

The model and actress, who was voted the sexiest woman in the world earlier this year by FHM readers, is the face of a new fragrance, Burberry Body.

The 24-year-old, who recently made her film debut in Transformers: Dark Of The Moon, was photographed by Mario Testino for the campaign.

Rosie is seen reclining and pouting towards the camera with an unfastened camel trench coat falling open to reveal she is naked beneath.

The beauty has modelled for the fashion label regularly over the past few years.

She said: "It's a huge honour to be working with Burberry again, a brand that put my career on the map and helped launch me."

Burberry's chief creative officer Christopher Bailey said: "Burberry Body is the most exciting launch that we have ever created and captures the iconic spirit of the brand today in a striking and sensual way.

"Rosie's effortless style and her staggering beauty made her the natural choice as the first Burberry Body."

Testino will shoot a portfolio of "Burberry bodies" over the coming years as part of the campaign.

The fragrance will launch in 150 countries from September 1.
