Rosie’s Diet Secret Revealed – And It Won’t Cost You A Cent

She’s one of the highest-paid supermodels in the world, has appeared in Hollywood blockbusters and even has her own lingerie line for M&S. 

But, if you think Rosie Huntington-Whiteley works hard for her body, think again, because the blonde beauty claims that her physique is down to drinking eight glasses of water a day!

The 25-year-old has credited Dr Batmanghelidj's book You’re Not Sick, You’re Thirsty! Water For Health, For Healing, For Life for helping her maintain her super slim shape and flawless skin.

Sharing her find with followers on Twitter, the statuesque stunner Tweeted, “A brilliant book I'm reading. We always knew water was good for us. Now discover why. Have you had your 8 glasses today??! #naturesmedicine #getdrinking #8aday #water #simple #safe #free #effective”.

Either Rosie has massive hands or teeny thighs...

The model, who is reportedly a size six, also Tweeted a picture of her hand, which appears to be as wide as her upper thigh.

We're pretty sure her daily gym sessions have more to do with that than guzzling eight glasses of water a day...
