Prince Louis has sent royal fans into a frenzy once again after a video of the young royal has resurfaced online.

In a sweet clip that went viral on TikTok, Prince William and Princess Kate’s youngest son can be seen collecting presents on the annual Christmas Day walkabout at Sandringham last December.

In the short video, Louis can be seen accepting a chocolate bar from a member of the public before saying: “Thank you.” The inclination of the youngster's voice led many fans to believe Prince William and Princess Kate's has a shy side to him.

The video has gone viral with over 27,000 likes, seemingly showing the six-year-old in a different light to the confident prince we usually see at royal events, dancing and pulling funny faces.

In the comments, people have been quick to praise the young prince and comment on his apparent shy voice as he accepts the gift politely.

One fan wrote: “Ohhh so cute.”

Another commented: “So sweet.”

The video isn’t the only moment Louis, six, caught the attention of royal fans on Christmas Day.

The sweet prince also made people smile when he was seen struggling to carry the many presents he had been given by generous members of the public, which included a teddy bear, a Cadbury selection box, a chocolate Santa and a Christmas headband.

Louis was carrying so much that he even received a helping hand from Prince William, who also asked some royal fans to keep the chocolate for themselves rather than giving it all away.

Louis’ siblings Prince George, 11, and Princess Charlotte, nine, were also equally spoilt with gifts from members of the public, including flowers for the young princess who won over fans when she was spotted posing for selfies.

After the walkabout, the royal children along with Prince William, Princess Kate, and the rest of the Royal Family, headed back to Sandringham for the rest of the day’s festivities.

The young prince is expected to be seen again at Easter when he attends a church service with his family.
