Chelsy Davy, the girlfriend of Britain's Prince Harry, cheered as 100 men stripped off and engaged in a naked dash on the last day of the Durban July meeting in South Africa.
The 22-year-old Zimbabwe-born beauty looked resplendent in a strapless white and pink flowered dress as she watched the event - South Africa's answer to Royal Ascot - but couldn't prevent her giggles when the eager racegoers ran in their birthday suits.
An onlooker said: "Chelsy was soaking up the sun in a VIP lounge for most of the day with her friend and clearly found the whole thing a hoot."
Chelsy is currently in Durban spending three weeks with friends, while Harry is helping to build a school for AIDS orphans in the nearby town of Lesotho with his charity Sentebale.
A source said: "Once Harry has finished in Lesotho, he and Chelsy are planning a safari in Botswana."
