Look Roo's in Dubai! United star's son Kai

Their life is certainly a series of holidays.

Coleen Rooney and her son Kai are enjoying the sun, sand and the sea during their latest holiday in Dubai, while England football star Wayne Rooney is on tour with Manchester United in America, as part of his pre-season training.

The latest trip to the emirate is the Littlewoods designer's third foreign holiday in six weeks. She recently spent a family break in Barbados followed by a holiday to St Tropez with Wayne, reports Daily Mail.

In the last year alone, Coleen has enjoyed no less than eight sunshine breaks, claims the paper.

Coleen and the tot were spotted playing with a dolphin in water in Dubai's Atlantis, The Palm on Palm Jumeirah, the emirate's man-made island (going by the protective yellow jacket that Coleen was wearing in the picture she uploaded on Twitter).

In the photograph, Coleen can be seen clutching her grinning son in her arms during a swim. The model and television presenter told her 280,000 followers on the social networking site: 'Kai is loving it! X'

In fact, the tot showed a real penchant for diving in water. Although he seemed ready to jump but at the last moment he slipped and took a tumble "ending up on his bottom with a look of surprise on his face", said the daily.

Earlier, Coleen had tweeted she was missing her husband, saying: 'Missing @WayneRooney.'
