Princes William and Harry put their polo skills to the test for a star-studded audience in Ascot, England, on Saturday. Helen Mirren and Clive Owen got in on the royal fun, chatting up the uniform-clad princes at the Audi Polo Challenge event. Helen — who first famously portrayed William and Harry's grandmother, Queen Elizabeth, in her critically acclaimed movie, The Queen — was all smiles as she mingled with the guys. This isn't the first time William has met the Academy Award winner — William presented Helen with an award at the 2014 BAFTAs, after which the actress sang his praises. "I don't mean this rudely, but you would never think that he was a prince, which to me is the biggest compliment you can make," Helen said.
William's had an action-packed week filled with sporting events. On Friday, he attended a soccer match between England and Peru at Wembley Stadium in London. After the game, the future king got a tour of the locker room, where he struck up conversations with a few shirtless players. Although Kate Middleton didn't join him for the game, the duchess was by his side for their official trip to Scotland on Thursday, where they sampled whiskey — and got giggly! — after greeting the big crowd of people gathered to meet them. Meanwhile, newly single Prince Harry has been focusing on his charity work. On Thursday, Harry inadvertently flashed his royal abs while playing sports with kids.
