Members of the royal family have rallied around Prince Philip to wish him a Happy Birthday as he turns 99.
The Duke of Edinburgh is currently remaining under lock down in Windsor Castle with his wife, Queen Elizabeth II.
And while his closest relatives were unable to see him in person for what was sure to be a birthday bash to remember, they've found other ways to make sure the Prince is feeling all the love on his special day.
On Wednesday, Kensington Royal led a stream of posts dedicated to the well-lived royal, with Prince William and Duchess Catherine sharing two candid snaps of themselves with Philip over the years.
"Wishing a very happy 99th Birthday to The Duke of Edinburgh!" They wrote alongside the pictures.
As for Philip's son and future King Prince Charles and his wife Camilla, the pair also used their widely followed Instagram platform to wish the Duke a happy day.
In another two images, Charles is seen with his father - the first when he was just a young boy, and the second more recently snapped where Charles and Philip are seen breaking into fits of laughter.
"Wishing The Duke of Edinburgh a very happy 99th birthday! 🎊," The royal Instagram account captioned the pics.
Princess Eugenie also shared a special post for her grandfather, adding an official image from her wedding day in 2018 featuring herself, new husband Jack Brooksbank, Princess Eugenie and the sisters' two grandparents, Philip and Queen Elizabeth.
Eugenie referenced the difference in celebrating a birthday in lockdown this year, writing: "A very Happy 99th Birthday to HRH The Duke of Edinburgh.
"Grandpa, we wish you a special day.. and may all grandparents celebrating birthdays in lockdown have a wonderful time. #happybirthday."
And possibly the most important tribute of all came from Buckingham Palace itself, the official account of which shared a number of pictures of Philip throughout his years.
"Wishing The Duke of Edinburgh a very happy birthday!" The Palace wrote.
"His Royal Highness turns 99 today and will spend the day with The Queen at Windsor."
We must say, this is quite the Instagram carousel.
Outside of Instagram, it's understood Prince Harry and Duchess Meghan, who recently moved to Los Angeles, also shared birthday wishes with the Prince via FaceTime.
Royal reporter Carolyn Durand, who is a writer for Oprah Magazine, shared some more details on Twitter: "A Source close to the #DukeandDuchessofSussex confirm that #PrinceHarry and Meghan with Archie will speak to The Duke of Edinburgh #PrincePhilip today to wish him a happy 99th birthday."
It certainly seems that just like us, the royals are very big fans of the old FaceTime natter!
And with so many birthday wishes, we're fairly sure Philip was definitely feeling very loved on his special birthday.
