The day out with Kate will mark Meghan's first time at Wimbledon as a member of the royal family, although she has attended in previous years.
The tennis star, who had previously remained coy about whether Meghan would be seen cheering her on, spoke out on Thursday after Kensington Palace confirmed the news. The Duchess of Sussex and The Duchess of Cambridge, came together to watch the Ladies' Single Final at the Wimbledon Championships. "And so when Harry told Violet he was having trouble finding someone, Violet said she might just have the ideal girl for him".
"To all the moms out there, I was playing for you today", she said. Since marrying Prince William in 2011, Middleton, 36, has been a regular Wimbledon spectator, attending with William or her sister, Pippa Middleton.
After Kerber defeated Karolina Pliskova to lift her second slam title at the US Open later that summer and climb to world number one, it seemed Williams might have a consistent challenger at the top of the game.
But after the semi-final between Novak Djokovic and Rafa Nadal was suspended at 11pm on Friday night, they also got the added treat of seeing that match resuming. Serena has made no secret of the challenges she's faced returning to the competitive circuit, from missing her daughter's first steps to making the decision to stop breastfeeding.
A new report claims that Meghan Markle and Kate Middleton are both pregnant at the same time. The pair had an overnight stay aboard the Royal Train before attending Royal Ascot, which was her Royal Ascot debut.
The Wimbledon Ladies' Single Final is at 2pm on Saturday. "I'm with royalty!" Williams can be heard saying in the selfie video she took of herself and Duchess Kate, who didn't say anything but smiled broadly.
