Princess Charlotte Adorably Reacts to Mom Princess Kate Receiving a Standing Ovation at Wimbledon. The young royal is clearly proud of her mother.

Kate Middleton received a moving standing ovation as she arrived at this year’s Wimbledon men’s final match amid her ongoing cancer treatment, and no one was more proud than her beaming daughter, Princess Charlotte.

On Sunday, July 14, the Princess of Wales arrived at Wimbledon in what was only her second official public appearance since she announced she has been diagnosed with an unspecified type of cancer. While Middleton has made it a point to attend Wimbledon every year as the patron of the All England Lawn Tennis and Croquet Club, this year her attendance was something of a looming question mark given her health.

So it came as little surprise that when Middleton arrived in a purple Safiyaa dress featuring a ruched bodice and softly flared skirt, the crowd gave her a standing ovation and her daughter reacted in the most Princess Charlotte way possible.

As Wimbledon attendees rose to their feat, Princess Charlotte beamed with pride while looking up at her mom. In response, Princess Kate waved back to the crowd, reportedly smiling as she grew visibly moved and emotional by the gesture.

In an interview with People, Karwai Tang—a photographer who was also present and who captured the emotional moment—said that the royal “usually comes in” and “walks down the step and into her seat.”

“She doesn’t normally stand and wave,” Tang told the publication. “But she stood for a while and took it all in. For her to acknowledge it and take in the applause was special.”

To mark her second official public appearance, Middleton appeared to post a “welcome back” message of sorts on Instagram, along with a few pictures of the royal at Wimbledon.

“Great to be back at @Wimbledon!” read the caption, which was shared on Kensington Palace’s official Instagram account. “There’s nothing quite like The Championships ?.”
