Princess Charlotte poses for fan selfies during Christmas Day walk

Forget royal duties — Princess Charlotte has been keeping busy with selfie duty!

Charlotte, 10, gamely posed for several selfies with fans during the royal family’s Christmas walk Thursday — to the point where she lagged behind her father, Prince William, and brothers Prince George, 12, and Prince Louis, 7.

“Charlotte,” the Prince of Wales called out in the viral footage, obtained by Hello! Magazine, encouraging his daughter to pick up the pace.

In the video, fans can also be heard comparing the young royal to her mom, Kate Middleton, and late grandmother, Princess Diana, as she shook hands and introduced herself to adoring crowd members.

“Look at her. She’s a Princess Di in the making,” one gushed.

Charlotte might have stolen the show with her charm during the walk, but her little brother Louis stole it with his mischief.

When William was handed a giant Lindor chocolate egg from a fan, the little one snatched it from his father, causing William to chuckle. 

William and Middleton, both 43, also attended a Christmas Day church service at St. Mary Magdalene Church with their three kids that day.

For the holiday outing, Charlotte wore a tan dress with brown tights and matching ballet flats, while her brothers opted for suits.

Middleton sported a plaid coat and brown boots, while William kept warm with a thick scarf around his neck.

Earlier this month, Middleton and Charlotte teamed up for a surprise piano duet at her fifth annual “Together At Christmas” carol service.

The mother-daughter duo played a rendition of “Holm Sound” by Erland Cooper. Middleton shared the touching video on Wednesday via Instagram.

The Wales family has been in the Christmas spirit all month long.

Charlotte and her brothers added a special touch to their mom’s Christmas service at Westminster Abbey on Dec. 5 when they decorated the tree with a long red paper chain filled with messages and their names in a sweet moment.
