The series of unearthed video clips of Princess Diana interacting with Prince Harry when he was a little boy have attracted attention from royal fans on Twitter. 

Shared by Twitter user Fahrah, the videos show the late Princess of Wales, who died in Paris after a car accident in 1997, sitting beside young Harry and William on what appears to be a balcony. 

In the clips, Harry can be seen whispering into his mother's ear, before she embraces him in a big hug. 

"Never saw this before. Imagine losing this," a caption behind the touching upload says. 

Gaining over 30,000 views and hundreds of likes and responses, the insight into Harry and Diana's incredible bond left royal fans emotional. 

"Pure love," one simply wrote. 

"Look at the love she had for Harry," another agreed, while one more wrote, "Such a sad loss for her boys. Such a beautiful loving mother."

Prince Harry reunited with his brother Prince William to mark what would've been Diana's 60th birthday on July 1st. 

 The brothers both attended the unveiling of Princess Diana's memorial statue at the sunken garden at Kensington Palace. 

One more comment beneath the Tweet pointed out just how difficult the milestone day must've been for the Duke of Sussex, but pointed out that he now has wife Meghan Markle and children Archie and Lilibet to lean on. 

"I can only imagine the heart wrenching pain he endured for years after losing her, this statue unveiling will be hard, but now he has the loving arms of his wife & children to go home to," the comment read. 

Prince Harry, who flew back to the UK without Duchess Meghan for the poignant event, recently shared details of the devastating memories he has of Princess Diana's funeral, during a chat with Oprah Winfrey. 

As part of their mental health documentary series, The Me You Can't See, Harry got candid about how the loss of his mother has impacted his mental wellbeing throughout his life. 

Speaking about how he and William walked behind Princess Diana's coffin at the funeral that was watched by millions worldwide, Harry said, "When my mum was taken away from me at the age of 12, just before my 13th birthday, I didn't want the life. Sharing the grief of my mother's death with the world.

"For me, the thing I remember the most was the sound of the horses' hooves going along The Mall, the red brick road.

"By this point both of us were in shock. It was like I was outside of my body and just walking along doing what was expected of me.

"Showing one-tenth of the emotion that everybody else was showing. You know, this is my mum. You never even met her."
