‘Shoutout to my bro @michael_ruffo_86 for his support during my cancer battle 👊🏽 & to all the other brothers and sisters out there supporting their siblings #forthesibs @ChildrensBrainTumorFoundation,’ Johnny wrote.
Alongside his poignant message, Johnny shared a photo of himself wearing a t-shirt that paid tribute to the power of brothers.
The t-shirt displayed the dictionary definition of brother as:
‘1 superhero
‘2 always helpful
‘3 someone to share childhood memories and jump in puddles with.’
Michael responded to Johnny’s post with his own comment.
‘Don’t know about the puddles,’ he wrote.
‘More like shooting spud guns together @johnny_ruffo.’
