In March last year, The Rock shared a long post to his Instagram in which he spoke about his relationship with his father.

Revealing he had bought his dad a new house, he wrote: 'Great chat with my old man. Felt good to my cold (heart) to hear him express his love.'

He explained: 'He’s a weathered soul and like all weathered souls, there’s often a harsh storied path that got them there.

'Well for my pops that path started at 13yrs old when his mom kicked him out of his house on Christmas day and forced him to live on the streets (very true and f****d up story) so his reality of compassion and love was forged thru pain and toughness.'

The Rock added: 'He raised me with that tough physical love and used to beat my a** in the gyms and on wrestling mats. I hated it then as a little boy, but grateful for it today as a man.'

The Rock, who has been on an eight-day tour across the U.S. promoting his new Teremana tequila brand, has yet to comment publicly on his father's passing.
