British model/actress Kelly Brook unveiled her nude billboard for Reebok EasyTone trainers this morning outside Battersea Power Station in South London. The giant ad is meant to trick women into believing that wearing the shoes will magically shape their droopy bottoms into something that resembles Brook’s altar of ass (You still gotta walk, ladies).

Brook told the U.K.’s DailyMail:

I’m so excited to finally have my own billboard, it was really fun creating the shot and Reebok EasyTones definitely got my bum ready for the occasion!

It’s a bit scary having yourself up on a billboard but I suppose I’ve got to get used to it because I just did a shoot for Playboy. It seems this month is my naked month!

August really is proving to be Brook’s naked month. The busty 30-year-old stunner can be seen making out nude underwater with porn star Riley Steele in Dimension Films upcoming fish-&-chicks frightener Piranha 3-D (Aug. 20).
