Even though Meghan's pal Serena Williams was ultimately beaten by Simona Halep in the match, it did nothing to dampen their spirits.
In one touching moment, Kate put her arm around Meghan in the ultimate sign of solidarity.
The Duchess of Cambridge showed her caring side to Meghan after a week where the Duchess of Sussex faced criticism for her parenting and her diva-like behaviour.
Meghan was mummy-shamed for the way she held her baby, Archie, on a day out at the polo on Wednesday.
She was also slammed after she reportedly instructed her royal security personnel to inform spectators at Wimbledon not to take photos of her at a game last Thursday where she was attending in "a private capacity" to watch Serena play.
The request caused an uproar from royal fans who dubbed the Duchess "Princess Privacy".
Kate's sister Pippa Middleton also joined the Duchesses in the royal box.
Prince William attended the men's final match with Kate on Sunday, as they watched Novak Djokovic beat Rodger Federer in an epic five-set match, which was ultimately won by Novak.
