The Duchess of Sussex and Duchess the Cambridge cheered on players at Saturday's Wimbledon final, as Serena Williams looked to secure her 24th Grand Slam title.
Meghan cheered on her close friend from the Royal Box. The tennis star had attended her wedding to Prince Harry last summer.
It will be the second trip to Wimbledon for both women this year – 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’s visit caused controversy after her royal protection officers told spectators not to take pictures of her while watching Williams on Court One because she was there “in a private capacity”.
She and two friends were pictured with rows of empty seats.
If the American wins against Romania's Simona Halep, it will tie her for the most women's Grand Slam titles in history.
When asked about the negative press, Williams said she never reads anything about Meghan in the news.
“She couldn’t be a better friend to me. Low moments, high moments, she’s always there,” Williams said.
“That’s all I want to be to her.”
Williams is just one match away from equalling the women’s record for the most grand slam wins.
The seven-time Wimbledon winner has a total of 23 grand slams under her belt – just one away from Australian player Margaret Court’s record of 24 which has stood since the 1970s.
An outing to Wimbledon could become an annual fixture for Meghan and Kate – they both watched last year’s women’s final between Williams and Angelique Kerber.
A spokesman for the Met Office said the duchesses ran the risk of some wet weather.
“There’s a fairly good chance that it’s going to stay dry but I couldn’t rule out a few showers around mid afternoon,” he said.
He said there was a 30% to 40% chance of the tournament seeing some rain.
He added: “Other than that it’s looking dry and bright with some sunny spells with highs of around 23C (73.4F).
