Man, time sure flies huh? It feels like just yesterday that Kate Middleton and Prince William gave birth to their middle child, Princess Charlotte, but the little darling just turned four years old on May 2. Hard to believe, right?

In honor of Charlotte’s birthday, the Duke and Duchess of Cambridge shared three adorable photos of their little girl. All three photos show just how quickly Charlotte is growing into a young lady.

In the first one, Charlotte is donning a lovely blue floral dress and blue sneakers, smiling angelically at the camera as she sits in the grass. She really is a beaut!

In the next two, Charlotte is wearing and a gray sweater and plaid skirt. In one of them, Charlotte is running toward the camera, holding out a flower from the garden at her home. In the other in the same outfit, she’s perched atop a fence, smiling and looking like a friggin’ teenager.

The photographs were taken in April at Kensington Palace and at their home in Norfolk and were taken by Kate herself.

This isn’t the first time photos of Charlotte were released for a birthday. Just last year, on her third birthday, the Kensington Palace shared the cutest photo of Charlotte wearing a red coat and pink woolen scarf. It was taken on her first day of nursery school.

All the new photos showcase her beauty and personality perfectly. Many people have said she looks just like her late grandmother, Princess Diana and her great grandmother Queen Elizabeth. We can totally see both resemblances!
