As Hasan Hasanov, who has been visiting the legendary tennis tournament for 15 years, took the picture before he was ordered by a royal bodyguard not to take snaps of the Duchess of Sussex.
After Serena's loss, Meghan and Kate gave Simona a standing ovation, as can be seen below.
The American tennis star ended up losing to Halep in straight sets.
However, it's not the first time that they have attended to Wimbledon together.
And their presence hardly went unnoticed.
The new nickname reportedly came as a result of royal security personnel reportedly asking a media consultant not to take pictures of the Duchess during a Wimbledon match.
This is the second year in a row the Duchess of Sussex and the Duchess of Cambridge attended the women's final.
They were joined in the Royal Box by Kate's sister Pippa Matthews.
For Meghan, the outcome of the match was probably not the one she had been hoping for.
Speaking to reporters after the final, Williams heaped praise on her friend Meghan.
By comparison, he said of the Sussexes: "Her name is certainly stamped on the innovative new brand of royalty that she and Harry are trailblazing, a brand that has promised much but as yet delivered only mixed results".
Meghan watched Serena play against Croatian pro Kaja Juvan on July 4 with friends Genevieve Hillis and Lindsay Roth. "Low moments, high moments, she's always there and that's all I want to be to her". "She, too, was happy for Simona".
The seven-time Wimbledon victor 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.
"It seemed insane to me because all I did was take a selfie to send to my wife", Hasanov said of his prime seats. "It's even more special now". "She's such a fan of the sport".
"You played an incredible game", Kate said. "And I'll stay a fan of the royals".
"I think that's just the way it's going to be".
The two duchesses arrived separately to SW19, with Kate first meeting some female junior players in her role as patron of the All England Lawn and Tennis Club.
The Wimbledon win is Snigur's first major title.
