Happy Birthday to Prince Louis, who turns seven today.

To celebrate the occasion, the Prince and Princess of Wales released a sweet new portrait of their youngest son—and fans across the board seem to be saying the same thing.

Louis, the third child of Prince William and Princess Kate, is the younger brother to Princess Charlotte, nine, and Prince George, eleven.

In the photo, Louis is pictured outdoors, perched atop what appears to be a tree stump in a woodland setting, smiling brightly for the camera. The portrait was taken by photographer Josh Shinner.

Royal watchers flooded social media with similar reactions, noting just how grown-up Louis looks in the image.

One fan wrote: “Prince Louis growing up. In long trousers (jeans even) and awaiting new front teeth. Terrific photo. Wishing Louis a fun family day, a delicious homemade cake and a great year.”

Another commented: “He’s suddenly all grown up. Happy birthday to Prince Louis!!”
And a third added: “Wow, so grown up all of a sudden! Happy Birthday Louis.”
“Wow! 7 y/o already!? Time flies,” said someone else. “Happy Birthday Prince Louis!! Hope you have wonderful birthday!”

Louis was born at 11:01 a.m. on April 23, 2018, at St Mary’s Hospital in London.
