The Queen will reportedly miss Meghan and Harry's son Archie's christening next month.
The Duke and Duchess of Sussex plan to invite family and friends to the bash, reports say.
But one notable exception to the guest list will be the Royal tot's great-grandmother - the Queen.
It's thought that the christening will take place in the first week of July, and that St George's Chapel in Windsor is the likely location.
The chapel is close to the couple's home - Frogmore Cottage - in Home Park.
It's also the same place Meghan and Harry were married, and the very same place the Duke was christened in 1984.
Archie - who was born on May 6 - will be two-months-old when he's baptised.The Sun reports that the Queen won't be able to attend because of prior commitments.
It's not the first time that Her Majesty has had to miss a family christening.
She was able to attend the christenings of Prince George and Princess Charlotte.
But she wasn't able to attend Prince Louis' ceremony last year.
Speculation is also circulating as to who might be on the guest list.
Reports say that Prince Charles and Camilla will be in attendance, as well as Prince William and Kate Middleton.
Meghan's mum Doria Ragland is also expected to fly over from California.
Archie's godparents, meanwhile, will be announced around the same time as the ceremony, and it has been suggested that friend and former stylist, Jessica Mulroney, will be among them.
