Nell McAndrew shows off her stunning figure in an itsy-bitsy black bikini

She famously loves her exercise - and the results are obvious as Nell McAndrew cavorts on the beach in the skimpiest of bikinis.

The model and marathon fan looked in perfect shape as she played with her son, Devon, in the sea during a family holiday to Dubai this week.

McAndrew, 34, was staying at the plush five star Le Royal Meridien hotel with Devon and property developer husband Paul Hardcastle, 38.

Wearing a tiny black bikini decorated with flowers, she displayed an enviably toned stomach and smiled broadly as she played in the surf.

But not one to neglect her motherly duties, she made sure that her 18-month old son was not similarly exposed to the sun and kept him covered up in the heat.

The part-time model from Leeds was clearly enjoying her holiday in the United Arab Emirates after releasing her fourth fitness DVD earlier this year.

The trip is something of a second honeymoon for the couple who married in November 2004.

They had a marriage blessing in December that year in Dubai and were clearly delighted to be back.
