British model-actress Kelly Brook has shed her clothes again, this time to advertise Reebok's new range of running shoes. The 30-year-old who recently posed naked for Playboy in a $ 500,000 deal, is the new face and body of Reebok's Easy Tone range of shoes, reported Sun online.

The model, who has just split from rugby hunk Danny Cipriani, will have the images splashed across billboards in the UK and US.

Brook, had earlier grabbed headlines with her naked lesbian sex scene in the upcoming film Piranha 3D.
