Patsy was speaking from her home in Malibu via video link, with Susanna asking about her life out in the US as her opening question.
However, Patsy said she was going to do “a real Piers Morgan” and walk out of the interview, explaining she was “not OK” with the show’s choice of description about her.
“You know what, actually, I don’t even want to do this interview because I don’t even want to look at what it says at the bottom of the screen,” she said.
“So I’m going to switch off, do a real Piers Morgan, and just say that it’s not okay to have ‘addict to wellness guru’ at the bottom of the screen.”
As Susanna and Ben tried to apologise, she continued: “My issues I had years ago, that were talked about by me many, many years ago and it’s over so I’m not going to talk about it.
“I don’t really want to talk to you,” she said, as she pulled down the lid of her laptop.
Ben said: “That was obviously a quote from Patsy’s book and it certainly wasn’t our intention to upset Patsy. We were keen to hear more.”
Susanna added: “I had no idea that was on our screen. That’s a terrible shame, our apologies to Patsy.
“She’s entitled not to do the interview, and we carry on,” she said before throwing to a weather forecast.
Last week, Piers made headlines when he stormed off set during a row about Meghan Markle with colleague Alex Beresford.
It came hours before ITV announced the divisive presenter would be leaving the show with immediate effect, following controversial remarks he made about the Duchess of Sussex’s interview with Oprah Winfrey.
