Prince Harry just revealed a rare picture of baby Archie to celebrate Prince Charles' birthday
Today, Prince Charles celebrates his 71st birthday - good for him.
And to celebrate the future King's big day, members of the royal family have been paying tribute to him on social media.
Prince Harry and Meghan Markle posted on their @SussexRoyal Instagram page, sharing a previously unseen snap.
The image shows grandfather Charles admiring at his grandson, Archie Windsor, after his Christening ceremony at Windsor Castle in July.
The post was captioned:
"Happy birthday to His Royal Highness The Prince of Wales - Sir, Pa, Grandpa!"
So sweet, right? Three generations all in one picture.
Of course, other members of the family have also shared birthday wishes to the Prince of Wales.
Harry’s brother Prince William and Kate Middleton also paid tribute to Charles on social media with a photo of Prince Louis and Prince Charles.
They wrote: "Wishing a very happy birthday to The Prince of Wales!"
Prince Charles' brother, Prince Andrew, posted another baby picture, of himself being held by older brother good wishes.
"Happy Birthday to The Prince of Wales! To mark HRH’s 71st Birthday, here’s photo from 1960 of the then Prince Charles holding a baby Prince Andrew."
