Kate Middleton and William share new snaps of Prince George to mark his seventh birthday

Britain's Prince George, whose seventh birthday is on Wednesday, was shown flashing a gap-toothed smile in two photos released to mark his seventh birthday.

The snaps, taken earlier this month by his mother Kate Middleton,  were issued by Kensington Palace late on Tuesday.

William and Kate’s three children are rarely seen in public and few photographs of them are released, but it has become a tradition for snapshots taken by  the Duchess of Cambridge, to be published on special occasions.

“The Duke and Duchess of Cambridge are delighted to share two new photographs of Prince George ahead of his seventh birthday tomorrow,” Kensington Palace said in a statement. It did not say where the photos were taken.

One showed George dressed in a dark green polo shirt, his hair neatly brushed, while in the other he wore a t-shirt with a camouflage pattern and his hair was tousled. He appeared to have lost one or more of his milk teeth.

Prince George Alexander Louis of Cambridge was born in the private Lindo Wing of St Mary’s Hospital in London in July 2013 and made his first public appearance a day later, when his parents stood on the hospital steps in front of a huge crowd of photographers and camera crews.
