Sadly, in November 2023, Johnny's family shared that the 35-year-old had passed away following his six-year-long battle with brain cancer.
"It is with a heavy heart that today we had to farewell our beloved Johnny," read the statement.
"Surrounded by his partner Tahnee and family, Johnny went peacefully with the support of some incredible Nurses & Doctors. He was a very talented, charming and sometimes cheeky boy. Johnny was very determined and had a strong will. He battled all the way to the end and fought as hard as he could. Such a beautiful soul with so much more to give."
