Kate Middleton’s latest outing is an ace. The Princess of Wales, 43, attended Wimbledon for the first time this year. She stepped out to watch American tennis player Amanda Anisimova and Poland’s Iga Swiatek face off in the women’s singles final on Saturday.

Prince William and Kate Middleton's three children were treated to a special gift from Wimbledon champion Jannik Sinner over the weekend. On Sunday, the future king and queen of England made a surprise appearance at the iconic tennis match, alongside two of their children, Prince George, 11, and Princess Charlotte, 10.

As many spectators watching from home clocked, however, doing so saw Kate break a major Wimbledon rule, in that hats are reportedly forbidden in the stands. The dress code for the annual sporting tournament is stated clearly on its official website.

Eagle-eyed royal watchers noticed the Princess of Wales debuted a twist to her late mother-in-law's stunning sapphire engagement ring at Wimbledon.

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.
