Not even Kate Middleton, poster woman for the prim and proper, can tame Nick Kyrgios. After losing his first Grand Slam title match to Novak Djokovic, the Australian tennis star flouted Wimbledon’s all-white dress code to receive his runner-up silverware from Middleton. Wimbledon requires that players wear nearly all-white clothing from the moment they enter the arena to the moment they leave the court, but Kyrgios slapped on a bright red Nike hat prior to the presentation. Some called him disrespectful on social media, with one British tennis writer calling the decision a “final act of defiance.” Indeed, Kyrgios’ match itself was not spared his defiant flair, as an umpire gave him a code violation for insisting—quite loudly—that an allegedly drunken fan be kicked out. “She’s drunk out of her mind!” he yelled, this time with a red face rather than a red cap.
