Jock also recently celebrated his wedding anniversary, taking to Instagram to gush about his wife.
“Every time I look at this picture of our wedding day I remember just how lucky I am to have found you,” he penned.
"From the second you tipped your hat and flashed that smile at me when we first met I knew that my world shifted, nothing would be the same again, that this moment was simply just meant to be," he continued.
He added: "I just can’t imagine a life without you & I’m so grateful to share a life with such an epic woman, leader, business women & mamma. I’m a better man, a prouder father and I hope a better husband."
Jock married his current wife four years ago after they tied the knot on New Year's Day 2017. They share their two children together, three-year-old Alfie, and five-month-old daughter Isla.
Jock also has two teenage daughters, Ava and Sophia, from his first two marriages.
While he eventually found love with his third wife Lauren, Jock was the first to admit that his previous drug use, combined with the antisocial hours and hospitality industry's intense culture, had a significant impact on his personal relationships.
"Two divorces, a handful of friends because you don't have the time to spend with them, so therefore you can count your close friends on one hand, and a deep mistrust of most people," he told the Adelaide Advertiser in 2014, reflecting on his time in the industry.
"That's what you're left with at the end of the day. Is it really that glamorous after all? I don't think so.''
Now, Jock has finally found peace and his "happy ever after" with Lauren, who is his partner in life and in business – working alongside the Scottish chef at their Orana restaurant.
