And since William made his little bro Prince Harry his best man for his own wedding back in 2011, we can assume that there's a high chance his brother will return the favour.
Prince Harry and Meghan Markle are all set to Wednesday on May 19, but his older brother might still be on a need-to-know basis when it comes to the role he'll play in the festivities.
Meghan Markle and Prince Harry attend Christmas Day Church service at Church of St. Mary Magdalene, Dec. 25, 2017 in King's Lynn, England.
While much attention was focused on the engaged couple's body language, Markle's interactions with the crowds and even her choice of outfit, there's one detail that appears to have slipped beneath the radar-the significance of the location of their visit. For those who are curious, she was born to Thomas and Rosalyn Markle in 1965, meaning that she is now 52.
Markle has shown us that she is not into frivolous, fussy, or over-the-top looks when it comes to her fashion choices, instead opting for simple, classic, elegant pieces. I was very happy to be there. "I had a lovely time, it was chilly in [the Abbey], but it was good".

Kensington Palace did not wish to comment.
The informant told the site: "Doria is outraged and has told Meghan that she's not going to let anyone push her or their family around - especially Camilla".
'When she walked into the room, I don't know what I was expecting, but as soon as she came in I was like: "Wow, I want to look like that"'.
William also said at the time that he and Kate are "delighted" for Harry and Markle.
