On Sunday, the world's most loved redhead, Prince Harry, celebrated his 35th birthday.
And while the internet was set alight with well-wishes for the father-of-one, it was one message and photograph in particular that had the world smiling.
To mark the special occasion, the Duke of Sussex' wife Duchess Meghan took to the couple's official Instagram account, Sussex Royal, with a stunning photo collage of the Prince.
Featuring several adorable photographs of Harry, including one of the late Princess Diana stepping out of a plane holding her young son, the photographs canvassed every aspect of the Duke's life.
But it was one photo in the bottom right-hand corner which had royal fans in a tizz - a never-before-seen photo from the christening of Archie Harrison Mountbatten Windsor.
The black-and-white photo shows Prince Harry kneeling down looking at his son, as Meghan sits on a chair (the very one where the large family photo took place) with Archie on her lap.
While the photo is quite small, Twitter user @daernerys has been able to blow it up (SEE BELOW) and it is magnificent.
Just look at Achie's little face!
Accompanying the photo was a sweet message from the Duchess.
"Wishing a very happy birthday to His Royal Highness Prince Harry, The Duke of Sussex! A birthday message from The Duchess of Sussex: 'Your service to the causes you care so deeply for inspires me every day. You are the best husband and most amazing dad to our son. We love you. Happiest birthday!'"
Of course, other members of the British Royal family sent their well-wishers, including Harry's brother, Prince William.
Taking to the Kensington Royal Instagram, the Duke of Cambridge shared this sweet photo (SEE BELOW) from Harry's wedding to Meghan, with the caption:
"Wishing a very happy birthday to The Duke of Sussex today! 🎂"
Prince Charles' official page, Clarence House, also sent well wishes to Harry - with a series of photographs of the Prince and his father.
"Wishing a very Happy Birthday to The Duke of Sussex, who turns 35 today! #HappyBirthdayHRH 🎂 📸 Chris Jackson Getty / PA," the message read.
In the next few weeks, Prince Harry and Duchess Meghan, along with baby Archie, will be embarking on a royal tour of South Africa - and we can't wait to catch a glimpse of the growing bub!
