To celebrate Prince Louis’ birthday today, a new photo has been shared — and Royal Family fans are pointing out who the young prince looks like.

The Prince and Princess of Wales released a sweet picture of Louis, their youngest child.

In the portrait, taken by photographer Josh Shinner, the seven-year-old is smiling brightly while sitting on what looks like a tree stump in a forest-like setting.

Many royal fans think Prince Louis looks a lot like his grandfather, Michael Middleton — Kate’s dad.

“Prince Louis takes after his grandfather,” one fan said.

“Looking very much like grandpa Middleton,” another royal admirer added. “Happy birthday Prince Louis.”

“Oh this baby is a Middleton through and through,” one X user commented.

“The Middleton gene is such a joy to see,” wrote another fan.

“He looks so much like Catherine’s father,” someone else pointed out.

Other fans noticed how much Louis has changed since the last time they saw him in photos.
