The eldest son of Prince William and Kate Middleton will ring in his milestone birthday July 22.
Happy Birthday, Prince George! The second in line to the British royal throne is celebrating a milestone birthday on Saturday, July 22. The son of Prince William and Kate Middleton turned 10, ringing in the occasion with a brand-new portrait, which was released on Friday.
The new photo of George was taken in Windsor, England, this month by photographer Millie Pilkington.
The eldest child of the new Prince and Princess of Wales has grown up in the public eye, starting off as a cheeky baby and growing into a passionate little boy.
ET's royal expert Katie Nicholl recently shared details on George's birthday celebrations.
"I'm told that this birthday party will be family, of course, close friends, friends from his old school, [and] friends from George's new school, but it's not going to be showy in any way," Nicholl shared. "A lavish party, where there's a huge expense, is just not William and Kate's style."
In honor of George's special day, look back at the little royals' sweet birthday portraits through the years:
