Prince Harry took Dave Grohl a gift while he was recovering in hospital after breaking his leg two years ago

Speaking to BBC Breakfast, he said: "When I had my surgery in London, he was one of the first people to visit me afterwards. He brought me a gift, he brought me this pillow to put my iPad on while I was in recovery.

"He's the sweetest... He came over and there was no entourage of anything."

The 'Run' rocker - who has daughters Violet, 10, Harper, seven, and Ophelia, three, with wife Jordyn - was particularly amused by the fact his nanny had no idea who the prince was when she brought his kids to visit the hospital.

He added: "It's funny, our nanny was there and she came into the room with the kids and I said, 'This is Harry'.

"And it took her about five or six minutes before she realised it was the prince of England. He's a very great guy."

Dave's bandmate, Taylor Hawkins, also told the tale of his own run-in with the British royal, who slapped the drummer to wake him up when he was complaining about jet lag just before he walked on stage for a concert.

He laughed: "I was like, 'what was that?' It was great, it was funny. I wore the slap with pride. He's one of the boys. What a boy. It's like Paul McCartney, once you break through the royalty, or the Beatles thing, you find they just want to hang out with the boys, like we do."
