Kelly Brook strips off for ad campaign

Actress and model Kelly Brook has unveiled two gigantic billboards showing her wearing nothing but a pair of trainers. The billboard follows in the footsteps of the 1994 Wonderbra campaign which showed a busty Eva Herzigova flaunting her chest which was much criticised for distracting motorists at the time. Brook said: "I don't want to cause any accidents but if it brightens up some builder's morning on the way to work then I have done my job, haven't I?." The ad campaign is for Reebok's EasyTone trainers, which the company claims improve fitness and muscle tone. Brook has recently returned from San Diego in America where she attended the comic book convention Comic-Con to promote the film Piranha 3D. She takes on the role of Danni and appears in a scene where she is filmed naked underwater.
