The rumours have followed Harry for most of his life.
For most of his life, Prince Harry has been followed by an ugly rumour that Prince Charles may not be his father... rather that his biological father was actually Princess Diana’s riding instructor James Hewitt.
The basis for the rumour was the fact that Diana and Hewitt did have a five-year affair, and over the years many have claimed Prince Harry bears a strong resemblance to Mr Hewitt.
But now, a photo of a young, Prince Philip (Harry's Grandfather) has gone viral on social media thanks to his “uncanny” likeness to his 34-year-old grandson.
The photo in question was taken in 1957, when Prince Philip was roughly the same age Prince Harry is now.
Getty photographer Chris Jackson snapped a photo of the vintage publication and shared it on Instagram this week with the caption: “I spotted this beautiful 1957 vintage cover of a @parismatch_magazine … Who does it remind you of?”
According to the UK’s Evening Standard, the old photograph is same uniform worn by Harry at the ANZAC (Australian and New Zealand Army Corps) memorial in Sydney over the weekend.
The post has since gone viral, receiving thousands of likes and 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, while another added: “What a find. Uncanny resemblance. Quite handsome both of them.”
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.
However, the royal family has always refused to make any official statements regarding the prince's paternity.
