As Wimbledon men's champion Jannik Sinner signed tennis balls for Prince George and Princess Charlotte, the Princess of Wales shared that they'd brought along a third ball for Prince Louis

In keeping with Wimbledon 's unofficial all-white dress code, which strictly applies to the players, Prince William wore white linen pants to attend the tennis tournament. A fairly unusual option for the Prince of Wales, who ordinarily wears autumnal shades, royal fans were quick to highlight the bold style choice.

Over the weekend, Kate Middleton and Prince William attended the Wimbledon Men's Singles final along with their two eldest children, Prince George, 11 and Princess Charlotte, 10. The nail-biting event on Sunday saw Jannik Sinner take home the first-place trophy in the tournament, after triumphing over reigning champion Carlos Alcaraz.

A fan posted a video of the Prince and Princess of Wales and their two oldest kids walking to their seats in the royal box at Wimbledon on Sunday.

Princess Charlotte sported a charm bracelet during her family's outing at Wimbledon. Get a closer look at the meaning behind the jewelry.

But she isn't the only famous face who will be looking forward to taking in the action today as A-list stars grace the royal box, including some members of Hollywood royalty. Today, fans saw billionaire Richard Branson was seen sat alongside the London Mayor Sadiq Khan.
