The other men in the crowd had their eyes glued to the cricket. But Chelsy Davy proved enough of a distraction to take Prince Harry's eye off the ball.

The young royal and his girlfriend appeared more interested in each other than in England's crucial World Cup match against Australia in Antigua.

While romantic observers mused that their behaviour was an indication of the depth of their love, the more down-to-earth members of Harry's circle favoured the explanation that cricket is not really his game. He always was more of a rugby man.

Either way, it is clear the couple are enjoying their three-week jaunt in the Caribbean in advance of the prince's deployment to Iraq as a troop commander with the Blues and Royals.

They spent their first week lazing around in the sun, smoking heavily and drinking Planters Punch in the exclusive Barbados resort of Glitter Bay, where they are sharing a private condominium.

Yesterday they roused themselves from their sun loungers to hop on to a private

plane to nearby Antigua.

Accompanied by two Scotland Yard protection officers and Zimbabwean-born Chelsy's brother, Shaun, the couple took their places in the stands without any fanfare.

Harry, 22, his arm slung around his girlfriend's shoulders, wore a striped polo shirt and sunglasses while Chelsy, 21, looked stunning in a green and white striped vest top and minuscule denim skirt.

The prince does appear to be picking up the cricket bug. Thanks to a close friend who is working for the World Cup security team, he and Chelsy also plan to attend England's match against Bangladesh in

Barbados on Wednesday. In recent days they have also been spending time with television presenter Jeremy Clarkson, who is holidaying with his family on the island's nearby Coral Reef resort.

On Wednesday Harry and the Top Gear star went fishing together before enjoying a long lunch followed by a game of tennis doubles.

On Friday night they dined together at the exclusive beachside Fishpot restaurant, a favourite of other celebrity holidaymakers including Sir Cliff Richard, Cilla Black and Tony Blair.

Unusually for Harry, who was recently photographed sprawled in the gutter outside a London nightclub, he and his girlfriend have been trying to keep a low profile.

One holidaymaker said: 'They are making a concerted effort not to even be seen together, but everyone knows who they are. Harry was in the pool when he was mobbed by children screaming "Prince Harry". He jumped out without saying a word looking embarrassed, although Chelsy smiled and said hello.'

The prince has been wearing a pair of bright red Baywatch-style shorts that almost match his sunburned cheeks. Bronzed Chelsy has turned heads in a blue and white polka-dot bikini.

The couple will return to England in two weeks when they plan to throw a going-away party for Harry before his six-month tour of duty in Iraq.
