Prince William and Kate Middleton are ringing in their daughter Princess Charlotte’s 8th birthday with a new photo of her gap-toothed grin.

In the smiling snap posted to the Prince and Princess of Wales’ social media accounts Monday, Charlotte put her missing teeth on display as she lounged in a hammock.

The little one sported a floral dress while relaxing with her hair down.

“Wishing Princess Charlotte a very happy birthday!” her parents gushed. “8 tomorrow ????????.”

The never-before-seen upload is part of the couple’s annual tradition, as William, 40, and Middleton, 41, have shared new pictures to honor Charlotte’s birthdays in years past.

When she turned 7 in 2022, the princess was all smiles posing with a dog while wearing a blue sweater and surrounded by flowers.

The birthday girl, who rocked a floral dress the year before, has volunteered for the elderly and played with toys in previous posts.

Charlotte was born in May 2015, two years after her big brother Prince George’s birth.

King Charles III revealed at the time that he had been “really hoping for a girl.”

The monarch, 74, explained, “She is beautiful. I was hoping for a granddaughter — someone to look after me when I am very old.”

Having a baby girl created a “very different dynamic” for William and Middleton’s family, the prince told “Talk Vietnam” viewers in 2016.

Two years later, the couple’s third child, Prince Louis, arrived.

Charlotte, who was once called “feisty” by her mom, has corrected both of her brothers’ behavior during multiple royal outings.

During the late Queen Elizabeth II’s Platinum Jubilee in June 2022, she fixed George’s posture on the Buckingham Palace balcony.

Later in the week, she appeared to scold Louis when he misbehaved during the festival’s pageant — but even she couldn’t stop his adorable antics from going viral.
