Meghan Markle, Duchess of Sussex, is a close friend of tennis star Serena Williams, who is currently playing in Wimbledon.
But will we see Meghan at the world’s biggest tennis event this year?
While Meghan attended Wimbledon two years ago as a guest of Ralph Lauren, she has not yet made an appearance this year.
The event started on Monday 2 July and ends on Sunday 15 July.
However, it is possible we may yet spot Meghan in the royal box at the tournament.
While Meghan is busy with a royal engagement in Dublin today and tomorrow, she is not committed to any other engagements this week.
This leaves her from Thursday through to Sunday to attend.
Serena Williams, whom Meghan met at a charity football match in 2014, has dropped a huge hint.
Asked by an on-court reporter whether Meghan would attend, Serena suggested she may on one condition – that she is “winning”.
She said: “I don’t know. We’ll see. If I keep winning.”
A further source told the Daily Express that Meghan may well turn up later this week.
“Meghan will not be at Wimbledon today,” said the source last Wednesday.
“If she was to attend, we would know two or three days before or on the morning of.”
Kate fans are hoping they will spy the Duchess of Cambridge at Wimbledon before the tennis championship ends next week.
Kate is currently on maternity leave after giving birth to Prince Louis on 23 April.
After having Princess Charlotte in May 2015, the Duchess’s maternity leave lasted six months and it is expected to be the same length of time for her third child.
While she will not attend official engagements until autumn, Kate will still be seen at other royal events.
Royal fans are hoping she will join Meghan Markle, 36, in a “Cambridge-Sussex double date” by attending Wimbledon.
Some fans have declared themselves on “Kate watch”, including blogger Royal Suitor, who wrote on Twitter: “With Federer and Serena playing back-to-back I think we may get a Kate-Meghan outing to see the last two matches.
