Meghan, Duchess of Sussex, center, on Court Number One to watch United States' Serena Williams play Slovenia's Kaja Juvan in a singles match during day four of the Wimbledon Tennis Championships in London.
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.
Meghan and Williams are close friends, with Williams attending her wedding to Harry last summer.
She said: "Just having her in general as a friend is great".
"I can't believe it", Snigur said.
"Always positive no matter what".
But the oil and gas safety engineer was just taking a selfie on his iPhone with the players in the background and was baffled to be asked by a minder: "Please give them privacy".
A spokesman for the Met Office said the duchesses ran the risk of some wet weather. Kate stepped out in a lovely green Dolce & Gabbana dress, which she previously wore during a royal outing with husband Prince William in 2016.
Both Meghan, who is now on maternity leave, and Kate watched the Wimbledon women's final in 2018, which Serena also lost in straight sets.
Their appearance marks exactly one year after Meghan and Kate stepped out for the first time without their husbands by their sides to watch the tournament together.
"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.
"I'm actually working on Olympia's game".
Poldark star Aidan Turner, actress Lily James and Doctor Who's Jodie Whittaker were also spotted among the Wimbledon crowds.
