Princess Kate stepped out in a new Self-Portrait blazer dress at a Buckingham Palace garden party on Friday, May 8, and she also revealed her latest sports obsession while chatting with guests. In a post shared by the Daily Mail’s royal editor, Rebecca English, on her Instagram Story , the journalist wrote that the Princess of Wales “revealed she has taken up padel .” The activity, which is similar to tennis and pickleball, but uses walls, is considered the fastest-growing sport in the world at the moment, so it’s no surprise that athletic Kate has got in on the trend. English wrote that Princess Kate told guests “it was a great game for non-tennis players (although that is her preferred sport).” Princess Kate speaks with guests at a Buckingham Palace garden party on May 8.
