Pregnant Princess Eugenie has shared an adorable video of her son August to mark his second birthday.
She took to Instagram to post the clip of her little boy running and along and chatting set to the music of Bee Gees hit Jive Talkin'.
Eugenie, who is expecting her second child in the summer, posted alongside the clip: "Happy 2nd Birthday to our boy Augie.. you are our world's greatest joy.
"Keep dancing and smiling my angel."
And of course, royal fans were quick to express their delight in the comments at seeing how grown up little August has become.
However, many couldn't help but note the uncanny similarities between August and Prince Harry and Meghan Markle's children Archie and Lilibet.
One fan, who thought he was the double of Archie wrote: "Cutie and he looks tall! At first I thought he was Archie."
While another said: "He and his cousin Archie resemble one another."
But others were more convinced of his likeness to Lilibet and said: "He could be Lilibet's twin."
Another said: "He does look like Lilibet, Duke and Duchess Of Sussex’s daughter."
While one simply added: "Aw he's just adorable. Augie, Archie and Lily are 3 peas in a pod."
Harry is known to be extremely close to Eugenie - and it appears she is the only royal to have visited him and Meghan in California since they quit the UK.
She was also the only royal to make a cameo appearance in their controversial docuseries, which dropped on Netflix last month.
Last month she shared a sweet family photograph of her son August kissing her bump to announce she is expecting her second child with husband Jack Brooksbank.
Buckingham Palace said the royal family is "delighted" and that August is "very much" looking forward to becoming a big brother.
The baby will be born 13th in line to the throne and he or she will be the first of the Queen’s great-grandchildren to be born since her death.
And according to royal expert and editor-in-chief of Majesty Magazine Ingrid Seward, Harry and Meghan would have been very much across Eugenie's news.
She told the Mirror: "The Duke and Duchess of Sussex would have been amongst the first to hear the news of Eugenie’s pregnancy.
"Meghan and Harry are close with Eugenie – and not only has she stayed with them in California, but they have been on holidays together before Harry’s marriage.
"If the Sussexes come to the coronation in May, there will be an added incentive to see Eugenie as by then it is doubtful if she will want to travel herself."
