Newly released photos of Britain's Princess Charlotte have gone viral on Chinese social media.

The British royal family released the pictures of the seven-month old princess, who has big blue eyes and chubby cheeks. In one, the fourth in line to the British throne smiles gracefully; in another, she gleefully plays with a stuffed toy.

"She looks just like her brother. Are you sure this isn't George mimicking Charlotte?", one Internet user said.
