Princess Charlotte is all smiles in her newly released birthday photos. 

The daughter of Prince William and Kate Middleton turns 4 Thursday and her mother took some adorable photos of her to mark the milestone. 

In one of the three photos released by Kensington Palace Wednesday night, Charlotte dons a blue flowered dress and sits on the grass at the family’s home. In another, she enthusiastically runs around in the grass smiling. The snapshots were taken in April. 

Kensington Palace captioned one of them on Instagram, “Happy Birthday Princess Charlotte.”

Charlotte is fourth in line for the throne. Her birthday comes right on the heels of that of her baby brother Prince Louis. He turned 1 last week. 

She may also have a birthday close to her new cousin, the child of Prince Harry and Meghan Markle, who is expected any day now.
