The Block's Ozman 'Oz' Abu Malik made series history last year when he took home a record $1.6million profit on the property he built with his best mate Omar.
And on Monday, the maintenance manager, 32, revealed he had another reason to celebrate after his wife Jasmin recently gave birth to Ali, their fourth son.
'We couldn't be happier. He's so special to me as Ali symbolises my time on The Block,' he told Woman's Day.
He added that his son may have been conceived during his stint on the hit renovation show which gave his birth a special significance.
'It could have been when Jasmin visited or just after filming had wrapped. It really is a Block baby!'
He then said he was thrilled his young sons were taking after him and predicted they may have a future on reality TV.
'They're very confident and I want them to have the best opportunities in life. So if something like The Block came around when they're of age, I'm happy for them to do that - it's the best thing I've ever done.'
Ozman and Jasmin are now the proud parents to four beautiful sons: Malik, eight, Zayd, six, Hunza, two, and baby Ali.
Back in November, Ozman and Omar made the largest sum over reserve of all five Block houses, selling their property for $5,666,666 and taking home a record breaking $1.6million in profit.
The Sydney-based best friends created a five bedroom, three-bedroom property with one of the biggest draw cards being its resort-style amenities include a solar heated pool.
The property also featured and a full-sized multifunctional court for tennis, basketball or soccer.
'We're absolutely stoked that we took out the win this year - we had a plan and stuck to it,' Ozman said at the time.
