Ed Sheeran has revealed some advice Prince William gave him at the Royal Variety Performance.

The singer-songwriter met the royal at the plush event in November.

Speaking to the Mirror, the 'Thinking Out Loud' star said William mentioned a recent pub duet Sheeran had with footballer Wayne Rooney in Manchester.

However, the royal said: "Er, no more duets with Wayne Rooney."

Sheeran continued: "I think they have a dude that preps them so they have one thing to mention. He knew something about all the people he met before me – it’s an amazing skill. I was like: 'Thanks for having me, mate. Nice one'.

"I don’t know if they’re fans. Do royals have iPods and things like that?"
