Whose model bod?The only thing doing any shedding in Blighty is the trees.

But this is a little more exciting than autumnal leaves falling - it's a bikini outing.

So we have a challenge for all you eagle-eyed celeb-spotters out there: can you name the owner of this superb figure?

We'll throw you a bone and tell you that she's of model like status (no surprises there then).

She's also hooked up with a Hollywood A-lister.

And she has been frolicking on the toasty beaches of Cancun, Mexico. Lucky lady.

But when she's not doing such taxing work she's strutting it down the runway or posing for the covers of fashion mags.

This bod has even made a couple of appearances in Sports Illustrated.

Any ideas or have we got you stumped?

Fret not, we won't leave you hanging - the rest of this beaut bod will be revealed in the gallery below, along with an array of other bikini-tastic stars.
