Ed Sheeran's dad "didn't believe" he'd been cut with a sword by Princess Beatrice

He said: "I have no idea how it came out as there weren't a lot of people there that night.

'For two weeks after, I had a huge gash on my face and would tell people I fell and then suddenly, the story came out...

"I remember telling my dad about it and he didn't believe me and said, 'No, what really happened?' "

But Ed insisted he can't be drawn on the details of the "alleged story" as he fears a backlash from the royal family.

He insisted to talk show host Graham Norton: "I can't talk about it. I don't know what will happen if I do!"

Despite being reluctant to discuss the incident, the 25-year-old star recently admitted he was left "completely covered in blood" from the cut.

He said: "I got hit in the face and I was like, alright, OK, and then started carrying on and then I looked down at my shirt and it was just completely covered in blood.

"And everyone was kind of gaping open-mouthed at me. What have I got a nosebleed or something? What's happened?"

But the experience hasn't put the 'Shape of You' musician off hanging out with royalty as he recently said he'd "have a lot of fun" with Prince Harry.

Asked to name candidates for an imaginary squad, Ed said: "Harry Windsor, because I don't really know him that well but I think I'd have a lot of fun with him."
