Prince George beams at the camera in a new photo released by Kensington Palace ahead of his second birthday.
Kensington Palace tweeted the picture, by Mario Testino, alongside the caption: "Look who's turning two tomorrow! #HappyBirthdayPrinceGeorge".
To mark George's second birthday the family are reportedly planning to hold a low-key celebration at their Anmer Hall country retreat on the Sandringham Estate in Norfolk.
Guests are expected to include George's great-grandmother the Queen, Michael and Carole Middleton along with George's aunt and uncle Pippa and James Middleton.
However, Prince Harry won't be attending because he is currently working on conservation projects in Africa.
Prince Charles and the Duchess of Cornwall will also miss the celebrations as they are on an official visit to the West Country.
