Prince William looks happy while Prince Harry appears sad in a rare throwback photo.

The Duke of Cambridge and Duke of Sussex were very close growing up. They were still so young when Princess Diana died in a tragic car crash and they grew up having each other’s back.

In this photo shared on Instagram, Prince William and Prince Harry’s closeness is visible. They are standing beside each other with the future king putting his hand on his younger brother’s shoulder.

However, the picture shows a stark contrast between the two from their outfits to their mood. Prince William is wearing a black top while Prince Harry dons a white polo button down shirt. Also netizens noticed that Prince William is smiling while Prince Harry looks sad.

“Prince Harry can look so sad sometimes!!!!” one royal fan wrote with a kiss emoji.

“Harry doesn’t look very well,” another user wrote.

Another fan said that Prince Harry might be tired so he looks unhappy. A number didn’t comment on the royal brothers’ disposition but acknowledged their close bond.

“William looks like his mommy so much [heart] I love how he loves and cares about his lil brother. Diana would be so proud!” one wrote.

“Nice picture of Prince William and Prince Harry. You can tell how much Love and care Prince William to his Brother,” another netizen opined.

Meanwhile, another royal follower said that she missed seeing Prince William and Prince Harry together. For months, there have been rumors claiming that the Duke of Cambridge and Duke of Sussex are feuding.

Prince William and Prince Harry’s beef allegedly started when Prince Charles and Princess Diana’s eldest son told his younger brother to slow down his romance with Meghan Markle. Prince William wasn’t supportive of Prince Harry’s plans to marry Markle because they barely know her.

In the past week, the Duke and Duchess of Sussex took a “tactless jibe” against the Duke and Duchess of Cambridge. Prince William and Kate Middleton were accused of trolling the Sussexes when they took a budget flight to Scotland amid the intense backlash aimed at Prince Harry and Markle for taking private flights. All of these only intesify the rumors that the fab four are really feuding.
