George of Cambridge turns two today, and to celebrate, Kensington Palace has released a new portrait of the cheeky prince by famed photographer Mario Testino.

The photo is a candid shot of the prince and his adoring Dad, with George baring his toddler teeth in a wide grin.

Dad Prince William also sports a big smile in the portrait, and seems to be holding on for dear life to the reportedly naughty prince.

• Charlotte’s country christening
• George steals the show

The photo was snapped by Testino, who also took some of the last portraits of Princess Diana, during Princess Charlotte’s christening at the Queen’s Sandringham estate on July 5.

George is dressed in a smocked set by Mum Kate’s go-to children’s wear designer Kate Riley.
