Kate Middleton and her three children Prince George, Princess Charlotte and Prince Louis were spotted having a fun time while cheering on father Prince William as he competed against Prince Harry in the match.

Meghan Markle was also there to give her husband support. The Dutchess of Sussex brought along her and Harry's baby Archie with her for the event.

During the event, Prince Louis continued to steal people's hearts with his cute antics. This time, the 1-year-old royal was photographed wearing his mom's oversixed sunglassed.

Kat also found the playful exchange amusing. Sitting nearby, the Duchess of Cambrigde was seen laughing while watching her son's cute action.
