Prince William, dressed in polo whites, joined his teammates at the Audi Polo Challenge in Chester, England, today. Prince Harry played in a similar tournament last month on behalf of his Sentebale charity, but this time around William competed for the organization Skill Force. William stepped out solo for the philanthropic appearance, and next Thursday he has plans to team up with his fashionable wife, Kate, for the Absolute Return For Kids gala dinner. The newlyweds welcomed President and First Lady Obama to the UK last week, and soon Kate and William will pay a return visit to the States. William and Kate's Summer trip to North America includes stops all over Canada as well as a two-day layover in LA. The photogenic couple are beaming on the July cover of Vanity Fair, which features never-before-seen snaps from their engagement photo shoot and details about their life as a married couple.
