We know that Duchess Catherine is a fan of the tennis, but she's not the only one in her family who loves a bit of courtside action.
On Monday, her younger sister Pippa Middleton and brother James Middleton attended Wimbledon and sat in the royal box to watch Serena Williams, Novak Djokovic and Roger Federer on Centre Court.
And once again, the mother-of-one proved she was a style icon in her own right.
Dressed in Stella McCartney, a designer favoured by the royals, Pippa looked the picture of elegance in her pink ensemble, accessorised with a wide-brimmed hat, tan high heels and a bag by J.Crew.
In fact, Pippa isn't the only royal to have that bag. Duchess Meghan stepped out with the same accessory when she watched her new husband Prince Harry play at the Sentebale Polo Cup last year.
We wonder if Pippa called into Frogmore Cottage on the way to borrow it!
Meanwhile, James Middleton looked as dapper as ever in his grey suit, paired with some stylish shades.
But as she entered the royal box, the youngest Middleton sister removed her head-wear, as it is frowned upon to wear a hat in that particular seated area.
"Protocol – dress is smart, suits/jacket and tie, etc. Ladies are asked not to wear hats, as they tend to obscure the vision of those seated behind them," reads Wimbledon's description of the royal box on their website.
At Duchess Meghan's first Wimbledon in the royal box, she too wore a similar-shaped hat and removed it once she was seated.
Of course, Pippa's stunning Wimbledon outing comes just days after her sister the Duchess of Cambridge attended the famed British sporting event.
Dressed in a white shirt dress from London based-boutique Suzannah, paired with a stylish Alexander McQueen belt at her waist, Duchess Catherine was the picture of sporty-chic and drew plenty of admirers.
As patron of the All England Lawn Tennis and Croquet club and a keen tennis fan in her own right, it was only appropriate that she attended.
As Duchess Catherine once described it: "Wimbledon is a quintessential part of the English summer."
And we couldn't agree more!
The British royals love to attend the tennis, but Kate and Pippa aren't the only ones by any means.
