An unearthed video clip of the late Princess Diana scolding a young Prince Harry to act accordingly is sending social media into a frenzy.

The video, shared by the Duchess of Sussex Instagram fan page on Monday, is taken from a documentary that aired on NBC in 2017, according to the Daily Mail.

In the early 90s footage, Diana is being interviewed by her voice coach, Peter Settelen, as Harry, now 35, is heard off-camera answering, “Yes, me!” after his mother is asked if she had met anyone who had “touched her heart quite a lot recently.”

However, Harry’s cheeky response didn’t go over too well with Diana -- who would have been in her 30s at the time. The royal mother, still keeping her composure, issues a stern warning to her youngest son.

“Harry, shush,” Diana warns as a young Prince William is heard piggybacking on his mother’s request, adding: “Yes, Harry, shush!”

Pressing on in her interview response, Diana continued: “I came across a great many people who um…” before adding: “I can’t even string my words together!”

Settelen then says to the Princess: “Well it’s hard, you’ve got two of the most impossible people sitting next to us," making reference to her sons.

“It’s all right, it’s all good practice,” Settelen added.

A clearly irritated Diana laughs before issuing her final warning: “Harry shush, just sit. Just sit!”

“Oh my gosh! This is adorable! 'Me,'" wrote one commenter, while another echoed the sentiment, adding: “The one and only Harry.”
