Prince Harry and Prince William were very close when they were younger.

The Duke of Cambridge and Duke of Sussex were too young when they lost their mom, Princess Diana. Growing up Prince William and Prince Harry were closer to each other than to their dad, Prince Charles.

A throwback photo of Prince William and Prince Harry with their mom Princess Diana was shared on Instagram. In the snap, the two princes wear uniforms and both look good in them. Princess Diana wears a red jumper with matching skirt. She stands behind her two boys.

While Prince William smiles at the camera, his younger brother’s attention is on him. Prince Harry smiles as he stares at his older brother adorably.

“Love how Prince Harry looks up to his brother,” one royal fan commented.

A different user said that there is so “much love” in the photo. Meanwhile, many said that the picture was “cute” and “sweet.”

On the other hand, another online user wondered what went wrong with Princess Diana’s two boys since there have been rumors claiming that Prince Harry and Prince William are fighting each other. Although the palace didn’t confirm it, their recent actions seemed to support their rumored beef.

“How is it possible that they are separated, always together, with so much love, that his mother taught him a unique being!” the fan wrote in Spanish.

According to previous reports, Prince Harry didn’t take it well when his big brother advised him to slow down his romance with Meghan Markle since they did not know her well. The Duke of Sussex accused the Duke of Cambridge of ruining his relationship with the former “Suits” star before it even started.

Prince Harry and Markle made a “tactless jibe” against Prince William and Kate Middleton in their past interviews. Prince Harry was accused of throwing some shades at his brother when he said he only wanted two kids to save the planet. Prince William is already a father of three.

Markle did the same to Middleton by saying that she doesn’t want to appear in a magazine cover because she didn’t want to appear “boastful.” The Duchess of Cambridge appeared on Vogue’s cover in 2016.

Many believed that the Duke and Duchess of Cambridge trolled the Duke and Duchess of Sussex when they took a budget flight to Scotland last month. It happened amid the intense backlash Prince Harry and Markle received for taking four private flights in 11 days.
