The photo that ends the rumours

There has always been a rumour following Prince Harry, but many are saying that this photograph might be the end of all that gossip. 

For most of his life, rumours have plagued Harry, that his father was not Prince Charles, but actually Princess Diana's riding instructor James Hewitt.

Diana and Hewitt did have a five-year affair, and many have claimed that Prince Harry bears a strong resemblance to Mr Hewitt — thanks largely to their shared red hair.

But now, a photo of a young, dashing Prince Philip has gone viral on social media thanks to his likeness to his 34-year-old grandson.

The photo in question was taken in 1957, when Prince Philip was in his mid-30s — roughly the same age Prince Harry is now.

It appeared on the front cover of Paris Match magazine, and shows Queen Elizabeth's husband, now aged 97, wearing a military uniform.

According to the UK's Evening Standard, the old photograph shows the elder royal "wearing the tropical dress of the Blues and Royals" — the same uniform worn by Harry at the ANZAC memorial in Sydney over the weekend.

Mr Jackson also posted a picture of Prince Harry wearing a similar outfit at his May wedding to Meghan Markle which many say also shows a striking resemblance.

The post has since blown up online and received countless comments.

"Think this photograph may put some of those ugly rumours to bed," one follower posted, while another wrote: "Let's put the James Hewitt saga to rest!"

Others claimed they mistook Prince Philip for his grandson at first glance.

"That's amazing! The resemblance is spot on. I thought it WAS Harry on the Paris Match cover and had to re-read the post. Awesome comparison," one Instagram user wrote.

However, some argued the resemblance might be less incredible if the royal pair weren't dressed in similar clothing with both sporting beards.

James Hewitt, now 60, became a household name in the mid-90s after publicly revealing his affair with Princess Diana, which took place between 1986 and 1991 — while she was still married to Prince Charles.

And in 2003, he made global headlines yet again after trying to sell 64 personal letters from Diana for £10 million — a move widely considered to be an act of betrayal.

Over the years, many have called for Prince Harry, the sixth in line to the throne, to take a DNA test to prove his lineage.

The palace has always remained tight-lipped on the matter and has refused to make any official statements regarding the royal's paternity.
