Kelly Brook hot pose for an ad

British model Kelly Brook has once again bared all, this time for a new Reebok advertisement.

The 30-year-old, who recently shed her clothes for Playboy magazine, appears in the ad wearing nothing but Reebok’s footwear EasyTone trainers, which is designed to tone bums and legs while walking, reports hollywood.

Brook is nursing a broken heart after splitting from rugby star Danny Cipriani. She is said to have thrown herself into her work to cope with it.
