The Princess of Wales is a regular at Wimbledon and last year, she was joined by her daughter, Princess Charlotte, and her sister, Pippa Matthews, for the men's final.
As patron of the AELTC, Kate gets to present the trophies at the end of the match before meeting the players behind-the-scenes.
But cameras caught a slightly awkward moment for Pippa while Kate was chatting to men's champion, Carlos Alcaraz.
The Princess was heard introducing her daughter to the Spanish tennis star, saying: "This is Charlotte, cheering you on," and as they finished their conversation, Pippa put her hand up and appeared to step forward to speak to him.

The Princess is expected to attend the tennis tournament in the coming days after it started on Monday.

Talking to cancer patients at the hospital's Wellbeing Centre, Kate said: "You put on a sort of brave face, stoicism through treatment, treatment’s done, then it's like 'I can crack on, get back to normal' but actually the phase afterwards is really, you know, difficult you're not necessarily under the clinical team any longer but you're not able to function normally at home as you perhaps once used to and actually someone to help talk you through that, show you and guide you through that sort of phase that comes after treatment I think is really valuable."

"You have to find your new normal and that takes time."
