Meghan is supporting her good friend and finalists Serena Williams, while Middleton is the royal patron of the All England Lawn Tennis and Croquet Club, the venue that hosts Wimbledon.
It will be the second trip to Wimbledon for both women - Kate made a trip to Court 14 to watch the UK's Harriet Dart, before heading to Centre Court to watch Roger Federer in action. Beautiful! New mum Meghan joined sister-in-law Kate, who was wearing a gorgeous green Dolce & Gabbana dress, first worn during her tour of Canada in 2016.
Serena Williams and Meghan Markle have been friends for a long time, with Williams attending Meghan and Harry's wedding past year.
She said: "Just having her in general as a friend is great".
She is reported to have said: "They have very similar personalities, which would make me believe trouble may well have brewed down the line". "And always positive, no matter what", she remarked, adding that the royal is also "happy for Simona".
Jephson claimed: "She knew it, accepted it and even turned it to her advantage: a couple of times a run of bad Press for her was miraculously reversed with a front page picture or a glossy magazine cover showing her at her most carefree and stylish in the Wimbledon sunshine".
The Duchess of Sussex arrived around an hour after Kate Middleton, who met with the players first. She had just been told she'd get the chance to meet the royal guests once she left the court and she replied with a big grin, saying "that's amazing".
This is the second event that they're attending as a duo, the first being Wimbledon previous year for the Women's final between Angelique Kerber and Serena Williams.
"It's an honor to play in front of the royal box", she shared, before learning that as the victor of the match-up, she would get a chance to meet Kate and Meghan. She saw she played unbelievable. Maybe she can give tips to him. "Actually she likes soccer more, so we'll see".
