- Markle was there to support her friend Serena Williams on Thursday, while Middleton opted to watch Roger Federer play two days earlier.
- The duchesses attended the tournament together last year.
- This comes after it was announced last month that Markle and Prince Harry are resigning from the charity they share with Middleton and Prince William — a possible sign that a reported royal rift is still ongoing.

Meghan Markle took a break from maternity leave on Thursday to watch her friend Serena Williams play at Wimbledon.
It was only the third appearance the duchess has made since giving birth to baby Archie on May 6.
She wasn't the only royal to attend the Championships this week.

Markle's sister-in-law, Kate Middleton, watched Roger Federer take on Lloyd Harris on Tuesday.
While Middleton dressed up for the event, donning a monochrome shirt dress, Markle opted for a more casual look.
The duchess wore jeans, a black t-shirt and a white blazer, along with a tiny "A" necklace, which is thought to be a tribute to baby Archie.
Markle is thought to have attended the event with university friends Lindsay Roth and Genevieve Hillis — the duchess' oldest friends, who The Sun reports could also be godparents to baby Archie.
Last year, the duchesses attended the tournament together.
They haven't been seen publicly together since before Markle gave birth in May. Since then, rumors of a rift between Markle and Middleton have only intensified.
It was announced by Buckingham Palace in June that Markle and Prince Harry plan to resign from the Royal Foundation, the charity they shared with Middleton and Prince William.
Royal commentator Richard Fitzwilliams previously told INSIDER that Prince Harry foreshadowed the split during the first — and only — Royal Foundation Forum last February.
"For months there have been rumors about difficulties in their relationship," said Fitzwilliams, former editor of "The International Who's Who."
"When Harry said at the only meeting of the Royal Foundation Forum held last February 'Working as a family does have its challenges,' few interpreted this as referring to any rivalry. Subsequently things have radically changed."
Harry and Markle also split households from Middleton and William earlier this year, relocating their staff base from Kensington Palace to Buckingham Palace.
However, it's possible the duchesses' individual Wimbledon appearances had nothing to do with the reported feud.
After all, it's clear that Markle would want to attend on a day that Williams was playing. The pair have been close friends for years now.
Not only did the tennis star attend the royal wedding in 2018, but she also reportedly cohosted Markle's lavish New York baby shower earlier this year.
