Royal Family Shares Adorable Photos Of Princess Charlotte To Mark Her First Birthday

The images were taken by her mom, Duchess Kate.

Happy birthday, Princess Charlotte!

The British royal family on Sunday released four brand-new photographs of the princess, to mark her turning 1 on Monday.

The adorable pictures were taken by her mom, Catherine, Duchess of Cambridge, at Anmer Hall -- the family's 10-bedroom country house on Queen Elizabeth II's Sandringham Estate in Norfolk, England.

In one of the shots posted to Twitter by Kensington Palace, the royal baby looks pensively into the distance with a bow in her hair:

In another, she is captured playing out in the garden.

A third photograph shows her staring at the camera, while in the fourth she props herself up on a wooden chair.

"We hope that everyone enjoys these lovely photos as much as we do," Kensington Palace wrote on Twitter.

We've watched the princess grow in a series of adorable photos released by Kensington Palace over the last year.

Pictures from March showed the princess playing in the snow with her older brother, Prince George, during a family skiing holiday in the French Alps.

The palace also released a set of equally cute images ahead of her turning 7 months old in November.

She was photographed alongside Prince George in June, when she was just 1 month old.

And Peruvian fashion photographer Mario Testino photographed Princess Charlotte's christening in July.
