Few supermodels achieve their figures through simple good genes.

And Naomi Campbell proved that she works hard for her amazing appearance when she was spotted getting in a little exercise during her holiday in Ibiza this week.

At 42, Naomi looked incredible in her skimpy black two-piece that displayed her long toned legs and flat stomach.

Miss Campbell fit some exercise into her otherwise relaxing day, doing some light water aerobics in the sea.

Her boyfriend Vladislav Doronin looked on as his beautiful girlfriend worked out.

Naomi showed off as much skin as possible in her brief bikini, but the Russian billionaire covered up in a T-shirt even in the water.

The couple are enjoying a break after flying from Austria where they attended the 20th Life Ball in Vienna.

Naomi, a longtime supporter, participated in a runway show to raise money for HIV and AIDS research.

Campbell appeared alongside Milla Jovovich, Karolina Kurkova and Keira Chaplin at the event.

Before that, Naomi had travelled to Bethlehem where she marked her 42nd birthday.

'As much traveling as I've done, I've never come here,' Campbell told a Palestinian television station during her low-key visit.

'I'm happy to be here. Weapons and war, greed and oil … I hope it all stops. I care about health, about good vibrations, not destruction,' she said.
