Prince Harry and Ed Sheeran's hilarious World Mental Health Day video

While World Mental Health Day isn't until October 10th, it is currently Mental Health Awareness week so we're throwing back to 2019 when Prince Harry and Ed Sheeran teamed up for a hilarious spoof video in honour of World Mental Health Awareness Day - a cause they are both extremely passionate about.

The surprise collaboration was a huge hit with fans.

The cheeky clip - which was posted to the Duke and Duchess of Sussex's official Instagram account - shows the two stars sitting in a cosy dining room chatting about the importance of discussing "a subject and conversation that is just not talked about"... that is before Ed has an awkward misunderstanding, thinking they are about to launch a 'Gingers Unite' campaign.

"This, for me, is a subject and a conversation that’s just not talked about enough, and I think people all over the world are really suffering," a serious Harry tells the 'Shape of You' singer.

Ed quickly agrees, saying that he’s been working on a song "to get it out to more people."

"People just don’t understand what it’s like for people like us," Ed says.

A confused Harry asks: "Yeah, I mean — what?"

"Well, you know, with the jokes and snide comments," the pop star continues as Harry's brow furrows deeper.

"I just feel like it’s time we stood up and said: 'We’re not going to take this anymore. We are ginger, and we’re going to fight.'"

A freshly enlightened Harry then addresses the "slightly awkward" situation, redirecting the conversation to World Mental Health Day as Sheeran sheepishly deletes the words, "HRH Prince Harry and the king of ging Ed Sheeran get together to change the perception of people with Moroccan sunset hair," from a laptop slide titled "Gingers Unite."

The pair then addressed the camera directly to highlight World Mental Health Day.

Harry said: "Guys, this World Mental Health Day, reach out and make sure your friends, strangers, look out for anybody who might be suffering in silence. We're all in this together."

Ed added: "Thanks for watching."

The project isn't the first time Harry and Ed have been linked, as the 'Shape of You' singer has had many ties to the royal family.

In addition to receiving an MBE in recognition of his services to music and charity from King Charles, the Grammy Award winner has a scar on his face from when his friend Princess Beatrice reportedly scratched him with a sword during a mock knighthood ceremony at a party.

Harry was also once mistaken for Ed by a group of schoolgirls in 2017.

This Mental Health Awareness Week is on 18 – 24 September and the theme is ‘Five Ways, Five Days’. You can find out more about it at mhaw.nz.
