Mia Tindallpoked some fun at her cousinPrince Georgeon Christmas!
In a cheeky momentcaught on camera(starting at 3:42 in the clip below) during the royal family’swalk from churchat Sandringham on Sunday, 8-year-old Mia playfully poked George, 9, in the back from behind as she walked past him. Prince George was greeting well-wishers with his parentsPrince WilliamandKate Middletonand siblingsPrincess Charlotte, 7, andPrince Louis, 4, when Mia attempted to distract him. Already a poised royal, George didn’t react when his second cousin tried to surprise him.
Mia is the eldest daughter ofQueen Elizabeth’s granddaughterZara Tindall, making her second cousins with George, Charlotte and Louis. Zara and her husbandMike Tindalloften bring Mia and their 4-year-old daughter Lena to royal family events (which son Lucas, 1, is still likely deemed too young to attend). In June, Mia and Lena sat behind their second cousins during Queen Elizabeth’sPlatinum Jubilee Pageant, where Mia similarly made silly faces and chatted with her family — much like Prince Louis’adorable antics!
Later, Mike (who sat next to his daughters and behind the Wales children at the pageant) opened up about what it was like to have a front-row seat to Louis' now-viral mischief.

“Louis, he was just wanting to have fun. And my two [daughters] are always mischievous, so it’s trying to keep a lid on. There were a lot of sweets out back though, so there was a real sugar high,” he added.
