Prince George celebrated his fifth birthday in July, and royal fans received a very special card after sending wishing the little one a happy birthday.
George turned five a few weeks ago, and reportedly celebrated the milestone surrounded by his close family in the exclusive Caribbean island of Mustique.
As he's so famous worldwide, it's no wonder Prince George received many birthday wishes from fans who've been following his journey since his mum Kate and dad William stepped out of the Lindo Wing, back in 2013, holding the tiny future king.
Turns out that people who took time to wish the little prince a happy birthday were lucky enough to receive a lovely thank you card from the royal family.
One royal fan shared the souvenir on social media, showing a picture of the card which features George's official fifth birthday portrait, taken by photographer Matt Porteous, which was also shared by Kensington Palace at the time.
Royal commentator Bradley Donovan-Baird wrote alongside a snap of the postcard: 'Wonderful postcard from the Cambridges thanking me for sending my birthday wishes to HRH Prince George of Cambridge. #royalletter #royalreply #Royal #princegeorgeofcambridge #princegeorge'.
He then posted another snap of the message that accompanied the cute picture, writing: 'Message on the back of the postcard. #royalletter #royalreply #Royal #princegeorgeofcambridge #princegeorge'.
Mr Donovan-Baird had also received a card thanking him for sending his best wishes to Prince Louis, for his christening, which he also shared on Instagram.
And it wasn't just Prince George fans who got a thank you card after sending their birthday wishes to a royal. Following Meghan Markle's 37th birthday, people who sent a message to the Duchess of Sussex also received a postcard saying thank you.
Following Harry and Meghan's wedding, the Palace also sent out lovely thank you postcards featuring a picture of the bride and groom, which read: 'The Duke and Duchess of Sussex have been overwhelmed by all the incredibly kind cards and letters they have received on the occasion of their Wedding, and are so touched that you took the trouble to write as you did. It really was most thoughtful of you and greatly appreciated by Their Royal Highnesses who send you their very best wishes.'
