The news comes after the young prince recently celebrated his ninth birthday and caught the attention of many royal fans who couldn't help but notice the future king is the "spitting image" of his father, William.
In a picture posted to the Cambridge's social media accounts, the eldest of William and Kate's children wore a light blue polo shirt and flashed the camera a big grin.
Captured by the duchess herself, the royals captioned the post, "George is turning 9!", before releasing a statement that said: "The Duke and Duchess of Cambridge are delighted to share a new photograph of Prince George ahead of his ninth birthday tomorrow".
George, who is third in the line to the throne, has been making more public appearances in recent months as he learns the ropes of royal life.
One of the appearances included his Wimbledon debut, which came 31 years after Prince William made his own debut at the tennis tournament.
Despite the heat, the young prince looked all grown up in a suit and tie for the appearance, and from the moment he stepped out of the car, all eyes were on him.
However, it was a photo of the youngster and his father overlooking the court in the Royal Box that had fans experiencing a feeling of deja vu.
The pair almost duplicated a similar photo shot of 9-year-old William and his mother Princess Diana at the 1991 Wimbledon championships.
Diana, in a patterned purple shirt, is seen pointing towards the court as a young William leans in – the pair watching the ladies final as Steffi Graf defeated Gabriela Sabatini.
Thirty-one years on, William, who is now a frequent attendee of the grand slam tournament, is seen posing in a similar position with George as they look out towards the court.
More than 1000 social media users have reacted to a post revealing the astonishingly similar photos.
"Lucky Prince George. William actually looks like his beautiful mother a lot," one Twitter user posted.
"Two future kings," wrote another.
