Are we seeing double? The series of pictures of Prince George released for his sixth birthday are freaking Royal fans out. The photos show just how similar the heir to the throne looks like his father Prince William.

Amazing resemblance: Prince George looks like Prince William

While Prince George's younger brother Prince Louis looks more like his mother, Duchess Catherine and her father, according to fans, George is actually the spitting image of his father when he was that age. Old photos of Prince William as a child make this especially clear.

"Wow, he looks exactly like his father", is the comment of a Twitter user. "At first I thought it was a photo of the young Prince William. They look so similar," writes another. Fans think Prince George has above all, the same smile as his father.

Like Prince William, Prince George is also a football fan

Prince George inherited not only the looks but also the enthusiasm for football clubs from his father. The little royal seems to be a big fan of England's National team!

Prince William is an avowed and enthusiastic fan of Aston Villa and has already expressed his football fever in several interviews. The Royal himself admitted that he also tries to get his children excited about the sport and it looks like it's working with George!
