She said: 'Easy Tones are luminous; it's like having a little gym built into your trainers. I wear them all the time in particular if I don't have time to get to the gym and then at least I know I'm doing something for my body.'They make your legs feel toned and bum feel pert, they are like magic shoes! I've been wearing them to tone up for the summer and have really seen a difference, which is why I didn't mind getting my hotpants on for the video.
'I had so much fun re-creating the advert - hula-hoping, trampoline, dancing around in my Easy Tones. My dog Rocky even got a guest appearance in the last shot!'
Kelly, 30, isn't the only celebrity fan of the innovative new trainers - Helena Christensen, Kim Kardashian, Whitney Port, Miranda Kerr and Bar Refaeli have all spoken about how impressed they are by the fitness shoes.
Kelly, who is currently in Los Angeles with boyfriend Danny Cipriani, has always spoken freely about her weight, and says it's sometimes a struggle to maintain her slimline shape.
She said recently: 'I enjoy healthy food and it makes me feel good. But it’s definitely not a crazy diet, I’m not going to deny myself desserts.
'I always try to have three meals a day and don’t snack on bad stuff. I like to make soups, which are healthy, filling and don’t make you feel bloated. I also love making healthy fish or vegetarian dishes.'
Kelly is also the face and body of lingerie brand Ultimo, and has been showing off her amazing figure in a series of flirty outfits while in LA.
After wearing a tight heart-print dress earlier this week, Kelly stepped out in a flowery playsuit to make the most of the LA sun.
