Prince George Gets His Own Winnie-the-Pooh Story -- See the Adorable Pics!

The young royal was written into his own children's book.

If this isn’t the most adorable thing ever, then we don’t know what is.

To celebrate Queen Elizabeth’s 90th birthday, a new story has been written and illustrated that centers on the children’s book character, Winnie-the-Pooh, who also happens to turn 90 this year.

In the tale, titled Winnie-the-Pooh and the Royal Birthday, Winnie-the-Pooh and his friends, Eeyore and Piglet, are joined by Prince William and Kate Middleton’s adorable 2-year-old son, Prince George, after Christopher Robin and Co. decide to go to London to honor the queen’s milestone with a red balloon.

“Behind The Queen ran a little boy. He was much younger than Christopher Robin and almost as bouncy as Tigger,” the story reads, describing Prince George. “He caught sight of Piglet and the balloon and he jumped up and down in delight.”

“The little boy patted Piglet fondly and tickled Winnie-the-Pooh’s ears,” it continues on. “Piglet handed him the beautiful balloon and he giggled and skipped away with it.”

The story, which was released Thursday and is available as a free download, was penned by Jane Riordan and illustrated by Mark Burgess.

On Wednesday, U.K.-based photographer Paul Ratcliffe shared a thank you card he received from Prince William and Kate Middleton for their fifth wedding anniversary.

“The Duke and Duchess of Cambridge were so touched that you took the trouble to write as you did on the occasion of their 5th Wedding Anniversary,” read the note, which featured a beautiful new portrait of the couple. “It really was most thoughtful of you and Their Royal Highnesses send you their warmest thanks and best wishes.”

Prince George has been stealing the show wherever he goes.

Just last month, the young prince -- who will turns 3 in July -- met President Barack Obama and First Lady Michelle Obama in his stylish silk pajamas at Kensington Palace.
