The reality TV personality opened up on IG Wednesday morning, sharing a heartfelt post with throwback pics of his father ... writing in the caption, "I love you Dad, I miss you. I’ll catch you on the other side ❤️✨🕊️."

The devastating news clarifies the cryptic Instagram Story he shared the night before, featuring a broken-heart emoji and a white dove atop a black background.

The rest of the pics show a close bond between Harry and his dad, with the final shot a particularly touching B&W photo of them holding hands.

In a series of IG Stories posted later Wednesday, Harry shared videos of some of his father's favorite rugby players sending their best wishes to his dad, revealing a battle with cancer over the past few months.

For now, Harry’s turned off comments on the post, but it’s clear his fans would’ve been flooding it with their condolences.
