The Lumineers drummer Jeremiah Fraites will never forget his encounter with Sir Elton John at the Grammy Awards earlier this month (Feb13) - he was given a swift slap after failing to believe the Rocket Man was a fan of the band.

The Ho Hey hitmakers were stunned to learn the rock icon had even heard of the group, let alone listened to their music, and Fraites couldn't help but call Elton's bluff - only for the veteran to put him in his place.

Singer Wesley Schultz tells London's Xfm radio, "We were nominated for two awards but didn't win. As we were walking in Elton John stopped us and said he has been listening to our album and was a fan. Our drummer said, 'There's no f**king way you are a fan!' Elton just slapped him in the face and put him straight. It was a special moment."

The Lumineers, who also performed at the Los Angeles ceremony, were nominated for Best New Artist and Best Americana Album for their self-titled 2012 release.
