Kate Moss has become the new face and body of St.Tropez.

The British model will be the focus of the self-tan and sun lotion brand's first-ever global advertising campaign, which aims to bring together women from around the world by encouraging them to post on Twitter when they are wearing the famous product when topping up on their golden glow.

Kate, 39, features in promotional pool-side photographs for the product, with one showing her laid out naked on her front and another showing her lying on her back in a glowing white swimming suit, both in which she is wearing the 'ultimate tan'.

Speaking about her participation, the blonde beauty said: ''I'm so excited to be working with St.Tropez. I've been using the products since they started and it's a really trustworthy, cool brand. I always feel more confident with a St.Tropez tan!''

Michelle Feeney - CEO of PZ Cussons Beauty, who own St.Tropez - is ecstatic the supermodel has agreed to come on board and hopes her iconic status will help raise awareness towards skin safety.

She said: ''We're absolutely thrilled that Kate Moss has chosen to work with us on our new campaign: it gives us the ultimate stamp of approval on the quality of our products.

''Kate epitomises St.Tropez's naturally glamorous approach to self-tanning and is a long-time advocate of the brand. As a global beauty brand with a heritage in tanning, St.Tropez is now in 18 countries and women from Rio to LA are seeking the benefits of safe tanning.

''Kate's fashion icon status is important to us but now her growing number of beauty campaigns proves that her appeal as a beauty icon resonates with confident women across all age groups globally. Not only is she beautiful but she has this amazing attitude. St.Tropez is about confidence.''
