Prince Philip and Prince Harry don't look the same, according to some netizens.

On Wednesday, Hello! shared a side-by-side image of the Duke of Sussex and the Duke of Edinburgh. Prince Philip's snap was taken years ago. The 97-year-old royal looked younger and seemed to be at his prime years.

"Prince Harry is the spitting image of Prince Philip – here's the proof," the caption read.

However, some netizens don't think the same. A number didn't see any resemblance between the two. "Nope I don't see it myself," Twitter user Sandra E commented.

"Errr... no," Carrie Clarke posted.

"Spitting image?? Ummm...I don't see it," ChocolaateDiva wrote, questioning the caption.

"Looks nothing like him.....He doesn't even look like Charles...." another user wrote.

Meanwhile, rumors have surfaced over the years about Prince Harry's true paternity. There were sources claiming that Prince Harry's biological dad is not Prince Charles, but James Hewitt. According to journalist Angela Levin in her new biography "Harry Conversations with the Prince," the Duke of Sussex was inspired by Hewitt to join the army.

"The soldier-mad toddler was fascinated by everything to do with the army, so it's no surprise he took to Hewitt straight away," Levin explained. "He wore a military uniform, rode horses and made his mummy happy. Harry was always incredibly close to his mother and when Diana showed strong feelings for Hewitt he followed her example."

Hewitt has denied the rumors about Prince Harry's paternity. According to him, Prince Harry was already a toddler when he met the late Princess of Wales.

"Admittedly the red hair is similar to mine and people say we look alike," Hewitt told Sunday Mirror in 2002. "I have never encouraged these comparisons and although I was with Diana for a long time I must state once and for all that I'm not Harry's father. When I met Diana, he was already a toddler."

According to Princess Diana's bodyguard Ken Wharfe, the speculations about Prince Harry's true father had greatly angered the princess. He also denied the paternity rumors.

"The malicious rumors that still persist about the paternity of Prince Harry used to anger Diana greatly," Wharfe wrote in the book "Diana: Closely Guarded Secret." "Harry was born on 15 September 1984. Diana did not meet James until the summer of 1986, and the red hair, gossips so love to cite as proof is, of course, a Spencer trait."
