Britain's Prince Harry is making his first formal visit to the United States for the second annual Veuve Clicquot Manhattan Polo Classic on May 30 on New York's Governors Island. Proceeds from the event will benefit American Friends of Sentebale, a charity that helps kids in Lesotho, Africa, which was founded in honor of his mother, the late Princess Diana. Harry, 24, who serves in the British military, will visit relatives of those who died on 9/11 and meet with American military personnel. (Photo: WENN)
