Prince William once unknowingly sparked relationship rumors between his mom, Princess Diana, and uncle, Prince Andrew.

Several years ago, the Duke of Cambridge was photographed with the two older royals and Sarah Ferguson during an engagement. Prince Andrew is in his military uniform, and he is holding hands with Prince William, who was roughly just 2 years ago.

Princess Diana is standing at the far end of the throwback photo, beside Ferguson. Prince William, who is in his blue trench coat, reaches out his hand to Princess Diana in an attempt to hold it.

The hilarious moment sparked reactions from fans who are still convinced that Princess Diana should’ve married Prince Andrew and not Prince Charles. On Instagram, one person commented that the Princess of Wales certainly married the wrong brother.

One royal fan also said that Prince Andrew was much more handsome than Prince Charles but Princess Diana loved Prince Charles more than she could ever love another man.

“Nobody knew Princess Diana and Prince Andrew were best friends since childhood,” the fan wrote.

One royal fan also said that Princess Diana and Prince Andrew looked good as a family.

Another said that it was so nice to see Prince Andrew bonding with his nephews especially when they were much younger. Princess Diana, on the other hand, also developed a close relationship with her nieces.

In another throwback photo, Princess Diana is pictured playing with Princess Beatrice and Princess Eugenie as Ferguson looks on. The photo also shows Princess Diana smiling from ear to ear while sitting on the grass. Princess Beatrice is on her lap, while Princess Eugenie is looking at her aunt’s direction.

Prince Harry is also featured in the photo and he’s sitting in between Princess Diana and Ferguson. The Princess of Wales and the Duchess of York used to have a close relationship with each other. But they had a falling out and never patched things up until Princess Diana death.
