Louis Theroux has revealed that his wife Nancy Strang has told him she would be 'OK' with him having an affair.
On the True Geordie Podcast, the documentary maker, 51, revealed: “She said ‘If you were ever thinking of having a relationship outside the marriage’ – or straying – I can’t remember how she phrased it, she said ‘I would be okay with that’.
“And I was like ‘Oh, well that’s cool’.”
But Louis said he could never cheat because he is a “stranger to myself” and “I don’t always know what I’m feeling half the time".
Louis lives a very private and happy life in his North West London home with his wife Nancy and their three children, Albert, 15, Frederick, 13, and six-year-old Walter.
Before the much-loved documentary-maker tied the knot with Nancy in 2012, he was married to writer Susanna Kleeman, who he met at Westminster at the age of 15.
Louis had always refused to discuss his marriage to Susanna, who has released a short memoir and novel, but was happy to explain why it was so controversial.
The TV star previously described his first marriage as a "marriage of convenience".
Louis and Susanna lived together in New York and decided to tie the knot for a reason other than love.
“You see, I was married,” Louis told The Financial Times in 2005. “What happened was that my girlfriend was living with me in New York.
“She was having trouble finding work...legally. So we got married, to make it easier for her.
“We never really considered ourselves married in the full sense – there were no wedding photos or anything like that.
“It was really a marriage of convenience. I hope that I am not going to get arrested for that.”
The former couple got divorced after three years of marriage from 1998 to 2001, then Louis went on to find romance with current wife Nancy.
TV producer Nancy has worked on several award-winning productions, including Timewatch and Imagine, during her 20-year career in the TV industry.
Louis gave a glimpse into his very private marriage while speaking to Clara Amfo on her This City podcast earlier this year.
He recalled spotting Nancy around London and being stunned by her beauty.
He said: "I began seeing her around the White City building. And I remember thinking 'wow, she’s beautiful'. She looked sort of like a French chanteuse.
"And she was sort of fashionable, but sort of not aggressively stylish. People didn’t really say 'hipster' in those days, but she had a touch of hipster.
"She would go out and smoke cigarettes outside in front of the building. I saw her on these little trips. I would pass her in the corridors as she went out to smoke cigarettes."
