Breaking News: In a delightful new photograph released to mark his 7th birthday, Prince Louis, the youngest child of the Prince and Princess of Wales, showcases his infectious joy with a beaming, toothless grin.

Prince William and Kate Middleton’s youngest child showed off his missing baby teeth in his 7th birthday portrait, released via social media Wednesday.

The little one was all smiles as he sat on a rock while wearing a navy sweater over a button-up shirt and jeans in the sweet new snap.

His top two front teeth are noticeably missing.

“Wishing Prince Louis a very Happy 7th Birthday! 🎂” Louis’ parents gushed via Instagram.

Many social media users commented on how “grown up” Louis looks, with many referring to him as a “big boy.”

While Middleton, 43, often is behind the camera for her kids’ annual pictures, photographer Josh Shinner took this year’s shot.

Middleton took a similar outdoor snap of Louis on a rock to honor her youngest son’s first year in 2019.

She and William, 42, welcomed Louis in April 2018, with baby No. 3 joining siblings Prince George, 11, and Princess Charlotte, 9.

For his second and third birthdays, respectively, he played with rainbow paint and rode a red bike.

The birthday boy marked his fourth year with a beach photoshoot, followed by wheelbarrow shots to honor turning 5.

Last year, Louis relaxed on a picnic blanket in the grass for his sixth birthday snap, taken by his mom

The little one has become best known over the years for his silly antics in public, from dancing at Trooping the Colour in 2024 to yawning at King Charles III’s coronation the previous year.

Most recently, he was photographed on a skiing trip with his family in the French Alps earlier this month.

Middleton, William, George, Charlotte and Louis skipped the royal Easter celebration over the weekend, instead celebrating privately at their Norfolk country home.
