A so-called ‘heavy metal grandma’ joined hard rockers Five Finger Death Punch onstage last night.

Ivan Moody and co. were performing at the Spektrum in Oslo earlier this week when they invited the older fan out onstage during popular track Jekyll & Hyde.

One fan filmed the footage, which you can check out below.

Five Finger Death Punch are currently on tour throughout Europe with special guests In Flames and Of Mice & Men.
