As Princess Kate continues her recovery, Prince William is set to attend London Climate Action Week solo, leading key events tied to his Earthshot and United for Wildlife initiatives.

Australian tennis legend Rod Laver previously confirmed Kate and William's competitive nature while speaking with The Sydney Morning Herald. "I'd met William and Kate a few times, and in the Royal Box you get a chance to chat with them a little bit," Laver revealed. "They play tennis against each other; William told me he couldn't beat her."

The shared Instagram account for Kate Middleton and Prince William welcomed a trio of guest posters Sunday, when children Prince George, Princess Charlotte, and Prince Louis took the platform over. The occasion: Father's Day, with a post in tribute to their dad, the Prince of Wales.
