Harry and Meghan have paid tribute to "mums all over the world" - including "Granny" - on Mother's Day.
The Sussex Royal Instagram account tweeted a photo with the words "Mummy, Mum, Mom, Mama, Granny, Nan."
The account captioned the image: "No matter what you call your mum, this Mother’s Day in the UK, we honour the mums all over the world who do so much every single day, and now more than ever."
The mention of Granny is believed to relate to the Queen.
Earlier, Kensington Palace tweeted: “To mothers new and old and families spending today together and apart – we are thinking of you all at this difficult time. Happy Mother’s Day.”
The tweet included pictures of the Duke and Duchess of Cambridge with their children; Diana, Princess of Wales with Prince William and Prince Harry; Carole Middleton with her daughter Catherine; and a card from Prince George to his mother for this Mother’s Day.
The royal family account also made a Mother's Day tweet. It chose a photo of the Queen with the Queen Mother.
The tweet said: “#MotheringSunday is a chance to thank and celebrate all mothers and caregivers, wherever they may be. So to all Mums everywhere, we are thinking of you, and wish you a very special Mother’s Day.”
While the account from Prince Charles' estate at Clarence House tweeted a photo of the prince as a young boy playing in the Clarence House garden with his mother in 1950.
Clarence House wished people a Happy Mother’s Day, “particularly in a year when families may not be able to be together”
The 93-year-old Queen, along with the Duke of Edinburgh, is socially distancing herself at Windsor Castle with a reduced household, having left London on Thursday.
Her eldest son Charles, 71, and the 72-year-old Duchess of Cornwall are reported to have moved from Highgrove in Gloucestershire to Birkhall in Scotland.
Over-70s are more at risk of complications if they catch the Covid-19 illness.
