“It never gets easier,” Clarke wrote.

“With the loss of my grandfather, I lost a best friend. I feel blessed to be surrounded by so much love on an extremely tough day.

“RIP Pop.”

Friends and family quickly grew around Clarke, who has been going through an emotional rollercoaster over the past few months.

Channel 7’s Larry Emdur was one of several people who have reached out to the ex-cricketer and media artist.

“Sorry to hear this news mate,” Emdur wrote. “I wish you and the family all the best.”

Businesswoman and socialite Erina Peters said: “I’m so sorry Michael! He really loved you so much.

“I have so many fun memories with him over the years and he never had a cheeky comeback.”

Clarke’s life was turned upside down when he got involved in a wild parking lot fight with now-ex-girlfriend Jade Yarbrough in January this year.

Video of the heated confrontation outside a Noosa restaurant went viral as Yarbrough accused Clarke of cheating on her with Clarke’s famous fashion designer, ex-girlfriend Pip Edwards.

Karl Stefanovic and his partner Jasmine Yarbrough, who is also Jade Yarbrough’s sister, were also present at the incident, which made headlines for weeks after the video surfaced.

Clarke said he took full responsibility for the drama and was “shattered” by his actions.

“I am absolutely disappointed that I have brought into this position people I hold in high esteem in this position,” he said.
