Meghan Markle, Kate Middleton attend Wimbledon together

The final weekend at Wimbledon is always a royal affair, but it was even more crowded in the royal box this year. Saturday became the day of the duchesses when Kate Middleton, Duchess of Cambridge, and Meghan Markle, Duchess of Sussex, made their first solo outing together.

The sisters-in-law were seated together in the royal box, first watching the end of the Novak Djokovic vs. Rafael Nadal semifinal (which Djokovic won in five) and then Serena Williams taking on Angelique Kerber. The royals are joined by Billie Jean King, Martina Navratilova, Emma Watson, Shonda Rhimes and more famous faces.

Serena's player box was also stacked with celebrities including Tiger Woods, Lewis Hamilton and Anna Wintour. But Middleton and Markle stole the show:

Markle is a longtime friend of Williams' and has attended Wimbledon before, though before she married Prince Harry and became royalty.

Middleton, a royal patron of the All England Club, also watched the men's final on Sunday, accompanied by Prince William. Novak Djokovic would make quick work of Kevin Anderson in straight sets.

ESPN's commentators got in on the royal fun, wearing hats for a segment of their show.

Even though Kerber would win in straight sets over Williams, 6-3, 6-3, Merkle and Middleton still got to be a part of something special on Centre Court.

Strokes of Genius is a world-class documentary capturing the historic 13-year rivalry between tennis icons Roger Federer and Rafael Nadal. It is timed for release as the anticipation crests with Roger as returning champion, 10 years after their famed 2008 Wimbledon championship – an epic match so close and so reflective of their competitive balance that, in the end, the true winner was the sport itself.
