Before joining the Foo Fighters, he was a drummer on tour for Alanis Morrisette and had a long career as a musician. He was going to release an album in a supergroup with Dave and Chris.
His sudden death shocked the music world as he was remembered as a talented and charismatic performer and a family man.
Cyrus told fans that she would dedicate her performance to him.
The Foo Fighters are yet to publicly comment on the death. In his book, The Storyteller: Tales of Life and Music, Grohl described his best friend and partner in crime as Hawkins.
I am not afraid to say that our chance meeting was a kind of love at first sight, and that it still burns to this day. We are meant to be, and I am grateful that we have found each other.
