Meghan Markle and Kate Middleton went on a sister-in-law date to the tennis

With the boys at home the ladies looked like they were having so much fun!

Kate Middleton and Meghan Markle left their husbands at home on Saturday as they took their first solo outing together watch the women's single's final at Wimbledon.

The new sister's-in-law ventured down to South West London to spend the afternoon in the royal box as Serena Williams faced off against Germany's Angelique Kerber.

The chic royals nailed their respective causal weekend looks with Meghan wearing a Ralph Lauren shirt with wide-leg cream pants and Kate opting for an elegant white and black polka dot dress, by British designer Jenny Packham.

While the match ended in an upset for new mum Serena, the Duchesses looked on as the tennis GOAT gave an emotional post-match interview on centre court.

In just her fourth tournament since giving birth to daughter Alexis Olympia Ohanian Jr., Serena told the crowd, "I was really happy to get this far."

Adding, "For all the mums out there, I was playing for you today."

It was the first time Meghan had attended the tennis in an official capacity (she has attended Wimbledon once before in 2016, the summer she met Prince Harry) so she took her lead from Kate and met with ball boys and girls, wheelchair competitors and junior tennis players before the match.

The two gals then seemingly spent the rest of the outing giggling and enjoying watching their good friend play.

Yes, more of these sister-sister dates plz!
