Prince George just turned 5 years old and many are already speculating how he would look like when he's 18 years old.

Daily Star commissioned an incredible age-progression image to show how Prince William and Kate Middleton's son may look like after 13 years. The stunning results reveal that Prince George will grow up looking like his father.

Prince George will retain his blonde locks. The expert used some of the Duke of Cambridge's features as a template to project his son's adult look.

"Firstly we decided to use his father Prince William as the template for an adult Prince George," Chad Bucannon of the Image Forensic Society explained. "Then it was a case of using a mixture of features from both of them, George’s eyes but William’s nose and mouth fitted best."

"We then layered them in different orders to achieve the final result, we used slimmed facial images of William for the teenage pics, but fuller faced pics for the final 18 year old portrait," the expert continued.

Just recently it was revealed that the Duke and Duchess of Cambridge are keeping a huge secret from the third-in-line to the throne. Prince William and Middleton are reportedly delaying the announcement to Prince George that he will become a king.

"With George, they are trying to delay that moment of realisation and give him normality before they thrust this on him," Catherine Mayer said in 2015. "But it will be, nevertheless, part of his upbringing both in terms of what he sees his parents and grandparents doing and probably quite soon a beginning of an understanding that he is in public life and what that means."

Prince William and Middleton wanted their children to grow up like other kids. As mental health advocates, they also want their children to be able to open up about their emotions.

"Catherine and I are clear that we want both George and Charlotte to grow up feeling able to talk about their emotions and feelings," Prince William said in a past interview. "There may be a time and a place for the ‘stiff upper lip’, but not at the expense of your health."
