Prince Louis Holds Hands with Cousin Mia Tindall During Royal Christmas Walk

In addition to his older siblings, Prince Louis has plenty of big cousins to show him the royal ropes.

On Christmas Day, the royal family made their annual outing to church. Prince Louis, 5, appeared with his parents, Kate Middleton and Prince William, and siblings, Prince George and Princess Charlotte. He was also seen holding hands with another young girl, Mia Tindall. Mia is the 9-year-old daughter of Prince William's cousin Zara, and William is also her godfather.

Mia seemed to have made her way forward in the procession with her parents, Zara and Mike Tindall, walking behind Prince Edward and Sophie, Duchess of Edinburgh. The Tindalls held hands with their 5-year-old daughter Lena, who walked between them.

The couple's youngest child, 2-year-old son Lucas, did not join the walk to church, likely too young to attend the service.

Following the church service, Mia was seen chatting with Princess Charlotte.

She then joined the others in greeting well-wishers who were waiting outside. At one point, Mia was spotted with a bouquet of red roses given to her by Princess Kate, who had accepted the flowers from a well-wisher.

In 2021, Prince William gave some more insight into his Christmas favorites and holiday traditions, including his children playing with other members of the family.

"For me, generally, bringing the family together at Christmastime is always lovely because we're quite spread out doing our things a lot of time throughout the year. We get very few moments to actually come together," the Prince of Wales said while appearing on a radio show. "When I see my children meet up with my cousin's children, and they all have a wonderful time playing together, it's very special. I look forward to that a lot."

Prince George, Princess Charlotte and Prince Louis clearly have a close bond with their cousins. Prince George and Savannah Phillips, the daughter of Prince William's cousin Peter Phillips and his ex-wife Autumn, were an adorable (and sometimes mischievous!) pair during several royal events.

The pair drew attention at the 2018 Trooping the Colour festivities. As the royal family gathered on the Buckingham Palace balcony to watch the flypast, Prince George caught a case of the giggles — prompting Savannah to cover his mouth and flash a deadpan look, seemingly knowing the cameras were watching. She was also seen placing a finger over her mouth to shush the future king. Also watching was Prince William, who looked less than amused by the little ones' antics!

Just one day later, Savannah and George reunited to cheer on Prince William at his charity polo match in Gloucester, England. During the playdate, which included running around the field and playing with a Slinky, Savannah playfully pushed Prince George down a hill when he attempted to sit next to her.

Though George wasn't injured and regained his balance, Savannah wasn't unscathed as she was scolded by mom Autumn immediately after.

Savannah's joking didn't end there, as she was also spotted ruffling George's hair when he wasn't looking.

The cousins were back to goofing off at Princess Eugenie's wedding in October 2018, where they served as members of the bridal party.

As they were waiting to walk down the aisle ahead of the bride, Savannah was spotted making George laugh by imitating the trumpet players providing entrance fanfare for the ceremony. Perhaps he realized the cameras were on him, as he was photographed covering his mouth.

After a 2019 playdate between Prince George, Princess Charlotte and Mia, an onlooker told PEOPLE, "They are all live wires with loads of energy."
