Royal fans were delighted after Meghan Markle shared a new picture of Prince Archie to mark his sixth birthday on Tuesday. The Duchess of Sussex took to her official Instagram account to upload a new snap of the young royal as she wished happy birthday to "our sweet boy" Prince Archie.

Meghan said in the post: "Our son. Our sun. Happy 6th birthday to Archie! Thank you for all of the love, prayers, and warm wishes for our sweet boy. He's six! Where did the time go?" She also thanked friends who celebrated at a recent party, writing: "And for all of you who came to celebrate with us at his party last weekend, thank you for making his birthday so incredibly special" - followed by a red heart emoji. The youngster was seen pictured from behind as he stood watching a vibrant orange sunset.

And royal fans could not get over how tall Archie looked in his latest snap and took to social media to express their views.

One user wrote on Instagram: "Sooo tall!!!!"

Another person said: "OMG 6 already that looks beautiful and tall just like his Dad Prince Harry, Happy Birthday Archie."

A third user commented: "Happy birthday dear angel. Prince Archie is a big boy now."

A fourth one added: "I can't believe little Archie is 6 already! Children really do grow up fast!"

A fifth one chimed: "He is getting tall. Happy 6th Birthday."

Archie's celebrations, according to mum Meghan, took place after the Duke of Sussex's bombshell interview with the BBC last Friday in which he said the King will not speak to him and he does not know how much longer his father has left.

Harry, speaking after losing a Court of Appeal challenge over his security, said he "can't see a world in which I would be bringing my wife and children back to the UK at this point".

Archie has made a number of appearances on Meghan's Instagram feed since the duchess launched her As Ever business.
