The renowned chef talked about Pierre White Jr — whom he calls “Little M” — in an interview with Event magazine, the Daily Mail has reported.
“Of course I didn’t watch Little M on TV – by watching it I would have been endorsing it,” he said.
“I work in TV. I understand the cynicism, but in my opinion that TV company is appalling for airing it, not because of my son, but because of all the other kids watching it.
“Where’s their moral compass?”
Marco Jr was shown having sex with model Laura Carter on Big Brother and sparked further outrage when he claimed to have blown a chunk of his father’s fortune on alcohol, drugs and prostitutes.
“The stories in the newspapers, they don’t bother me”, his father said about the claims.
“Worse things have happened to me in life and I have learnt you have to take the rough with the smooth.
“I get dragged in to these stories because of who I am and my position, but the truth is I’ve never met this businessman or introduced him to anyone.”
The celebrity chef said his son was staying at the family’s farm in Wiltshire.
