London, England (BANG) - Britain's Prince Harry accidentally flashed his underwear to a hoard of female onlookers. The 24-year-old royal went into a changing tent to get out of his sweaty clothes after playing in a charity polo match, but exposed his black boxer shorts to the world after he forgot to put the curtains of his tent closed.

A source told Britain's Daily Star newspaper: "A lot of girls hang around hoping for a glimpse of the princes but this time they got a real eyeful. When Harry spotted his audience he broke into a huge grin."

William - who also played in the polo game - was less shy than his brother, choosing to strip off in the middle of a car park.

A fan said of the trainee pilot: "He's clearly been working out with all that military training."

This is not the only time the royal brothers have amazed onlookers recently.

Last week, William joked about the color of Harry's hair, much to the horror of anti-bullying campaigners.

Harry - who was celebrating with William at RAF Shawbury after passing his exams on his way to become an army helicopter pilot - said: "I think he's definitely got more brains than me, I think we established that from school. . . and his baldness."

William then retorted: "It's pretty rich coming from a ginger."
