After a romantic safari in Botswana with Prince Harry, his girlfriend Chelsy Davy returned to the urban jungle with a bout of serious shopping.

Accompanied by her mother Beverley, the 22-year-old student spent several hours in the boutiques of King's Road, Chelsea.

Mrs Davy, who is in her late forties, was a beauty queen in her native Zimbabwe.

Harry: A few days of leave left

The prince, a lieutenant in the Blues and Royals, has a few more days of annual leave left before he returns to duties after the Bank Holiday weekend and plans to spend it with Chelsy, who is studying for a post-graduate law degree at Leeds University.

He has spent much of the summer in Namibia on adventure training with his regiment.

It is reported that Chelsy and Prince William's girlfriend, Kate Middleton, might make their first formal appearance together at Prince Charles's 60th birthday ball.

Although invitations to the Buckingham Palace event in November have yet to be sent out, royal sources have indicated that the girls are likely to be put on the guest list.

The black-tie event --which includes a formal banquet - is being thrown by the Queen in honour of her son on November 13, the day before his landmark birthday.

Although Kate and Chelsy have attended a number of functions alongside senior membersof the Royal Family - most recently the wedding of Princess Anne's son Peter Phillips - they have not been invited to a formal palace reception before.

According to royal protocol, only wives and fiancees are included on the guest list for such functions.
