Marco Pierre White fell out with fellow celebrity chef Matt Preson last year when he suggested his son had gone off the rails.
But it seems the British chef hasn't forgiven the Masterchef host over his comments, in which he accused Marco Pierre White Jnr of using drugs, and was visibly still angry over the incident when asked about it on Sunday Night.
When talking with journalist Melissa Doyle, the atmosphere turned sticky when she asked if Matt Preston had "crossed the line by talking about your children?”
"You know the answer to that,” he replied.
However, the fiery chef didn't want to divulge any more details about their long-running fight.
“I don’t have to get involved," he said. "Don’t ask me a question I’m not going to answer and don’t try and draw me into something I won’t be drawn into.”
The uncomfortable interview comes after Matt Preston made comments about Marco Pierre White's controversial son Marco Pierre White Junior who caused a stir for his antics on Celebrity Big Brother in the UK.
Marco's son shocked even more when he spoke out about his drug and alcohol abuse last May, saying he'd buy prostitutes with his father's money and admitting to having spent over AU$500,000 on drugs.
Matt Preston appeared on the Kyle & Jackie O Show last year after Marco Pierre White Jr's shocking confession, and suggested his colleague's son was off the rails.
"Anyone who's got tattoos on their face normally behave badly, don't they?" he said at the time.
When Kyle and Jackie asked if he was shocked by Marco's son's behaviour he replied with, "That's that whole rich, London trust fund babe, trustifarian-type stuff - it's another world."
It seems like there's still a lot of heat in the kitchen, and these two chef's are cleary not putting the fire out anytime soon.
