Yesterday, the Duchess of Cambridge sat next to her sister-in-law in the royal box for the women's final, with Meghan Markle, aka the Duchess of Sussex, turning up to support her friend Serena Williams (the American didn't win, Romanian star Simona Halep took home the title).
Today Duchess Kate, who is the patron of the All England Club where the Wimbledon tournament is played, sits next to her husband Prince William to watch the men's final.
Kate is wearing a Cartier watch, and a pale blue dress by Emilia Wickstead, which she hasn't been seen in before.
The pair turned up to the club early together, and waved at crowds as they arrived.
Other celebrities that have been spotted so far include Amazon CEO Jeff Bezos, Katherine Jenkins, Benedict Cumberbatch, James Middleton, Tom Hiddleston and Stanley Tucci.
Here are the pictures of Meghan and Kate at the women's final yesterday:
