Many found Princess Charlotte sweet during the royal family's Christmas walk.

Princess Charlotte, 8, and Mia Tindall, 9, displayed their sweet cousinly bond when they joined their family for their annual tradition of meeting the public after attending the Christmas service on Dec. 25. A clip uploaded on TikTok featured the two young royals along with Prince William, Kate Middleton, Prince George, Prince Louis, Zara Tindall and more.

Mia noticed that a crowd member wanted to give the Duke and Duchess of Cambridge's only daughter flowers, so she got her attention. Princess Charlotte told her cousin, "You take them." Mia came over to accept the flowers with a smile. Zara also saw the interaction between Princess Charlotte and her daughter and smiled. 

The video received warm responses from royal fans. 

"When Charlotte let Mia get the flowers, she felt happy and included," one wrote with a growing heart emoji.

"Charlotte and Mia are so cute the way she said you can get it, Mia was so happy!! [face holding back tears emoji] I love this," a second person commented.

"Yeah, Mia was so happy when Charlotte let her get the flowers [face holding back tears emoji] Charlotte is so kind [red heart emoji]," a third person said.

"George also gave Mia the bouquet that he got. These kids are amazing," a fourth person opined.

"Zara looking so proud at Mia [red heart emoji] it's amazing to see that Will and Zara kids have the same bond as Will and Zara," another royal family fan said.

Prince William and Kate Middleton have maintained a tight bond with Mike Tindall and Zara Tindall, Mia's parents. The two families are often seen together, even outside their public duties, and the children have noticeably developed a tight bond.

Mia was spotted walking hand in hand with Prince Louis to the church service and bonded with Princess Charlotte after the mass. The Princess of Wales also handed Mia a bouquet during the walkabout.

Charles Rae, former royal correspondent for The Sun, previously commented on the Tindalls and Waleses' close relationship after the Christmas walkabout. The royal expert claimed that the Prince of Wales found a brother in Mike after Prince Harry left the royal family.

"Now, sitting back in Montecito is the real brother, and I should imagine if he's seeing scenes like that and reading things like what they've been having in The Telegraph. He's not going to be a happy bunny at all, but that doesn't matter," Rae said on GB News. 

"Tindall fills that gap that I think the Prince of Wales needs, and he does it very, very well. Mike Tindall, he is a man's man. There's no question about that."
