Prince Harry Once Slapped the Foo Fighter's Drummer, Taylor Hawkins, Apparently

• During a recent interview on The Howard Stern show, Foo Fighters band members Dave Grohl and Taylor Hawkins talked about their experiences with Prince Harry. 
• Grohl shared that the royal was "cool" and helped set him up to comfortably watch his iPad and relax once when he was recovering after hurting his leg on tour in 2015.
• Hawkins, on the other hand, shared a story about a time Harry slapped him in the face to wake him up before the 2014 Invictus Games, which Harry founded. "I mean, I got slapped in the face by the prince," Hawkins said of the incident, which he says was in good fun and not offensive at all. "That’s OK, really, when you think about it."

Any encounter with the royal family is a story you'll tell for the rest of your life—even, apparently, if that story involves a royal literally slapping you in the face to wake you up.

In a recent interview on The Howard Stern Show Friday, Dave Grohl and Taylor Hawkins of the Foo Fighters shared the story of their own royal run-in with Prince Harry.

The encounter went down in 2015, when Grohl had hurt his leg during the band's tour of Europe.

"He brought me this thing to hold my iPad so I could just watch movies and sh*t. It was great. He was cool," Grohl explained, according to Us Weekly. "He smacked Taylor in the face one time."

The slap in question apparently went down before the 2014 Invictus Games.

"It pissed me off, actually," Hawkins joked before telling the story and making it clear that the slap was in good fun—and not, you know, actually offensive or, worse, assault. "He walked in and goes, 'How are you doing?' I said, 'I can’t wake up. I’m so tired.' He just goes bam and I went, 'You motherf*cker.’ He was like, 'Are you awake now?'"

Hawkins has a great attitude about the incident, clearly.

"I mean, I got slapped in the face by the prince," he added. "That’s OK, really, when you think about it."
