As any model worth her designer bikini knows, there's no such thing as a bad photo - only a bad angle.

So Jerry Hall, firmly putting the memory of that unflattering one-piece swimsuit shot behind her, strode out confidently on the beach in St Tropez this week.

The 52-year-old model and actress showed off a trim, toned figure in a colourful bikini that emphasised her enviable curves.

Perhaps she had been inspired by the widespread admiration for the red bikini that Oscar-winning actress Helen Mirren, 63, wore recently on an Italian beach.

Or perhaps she was just enjoying her newly-trim figure, said to be the result of a Mediterranean diet and plenty of exercise in the sun.

It was way back in 2001 that the one-piece swimsuit she was wearing in St Tropez suggested that even models succumb to the bane of cellulite.

At the time, Miss Hall insisted the dimpling on her legs was a trick of the light and subsequently appeared in a different swimsuit to show off her figure.

Then just six weeks ago, at the start of her break on the French Riviera, the Texas-born model was pictured boarding a friend's yacht outside the Club 55 beach restaurant.

And unfortunately for her, it seemed she'd brought her cellulite along for the ride as well.

In her latest beach pose however, the lady whose leggy look enchanted ex-husband Mick Jagger for more than 20 years looked as smooth and sleek as ever.

Miss Hall has four children by Jagger. Two of them, Elizabeth and Georgia May, are also models. The family live in a mansion on Richmond Hill in South-West London.

Jagger and his long-term girlfriend L'Wren Scott are renovating an equally grand home in Chelsea which he bought for £8.7million two years ago.

While Miss Hall appeared to be enjoying a solo holiday in France, Jagger has taken Miss Scott to the Caribbean island of Mustique where he owns an estate called Stargroves.
