The pair encountered one another at the Royal Variety Performance and the comic invited the duchess to appear on his hit series.
Father-of-two Widdicombe presents the hit series Parenting Hell with friend and fellow comedian Rob Beckett in which they chat to celebrities about the trials and tribulations of modern-day parenthood.
Widdicombe encountered Kate at the Royal Variety Performance in November, and revealed his agent bet him £100 he would not ask the duchess to appear on his podcast.
The duchess, mother to Prince George, Princess Charlotte and Prince Louis focuses her charity work on the early years of childhood and its crucial impact on outcomes in later life.
But Widdicombe told ITV’s Good Morning Britain (GMB): “She brings up parenting because it’s what I spoke about in the stand-up, and I was like, this is my chance. And I said, ‘We’d love to have you on the podcast’.
“I’ve never seen someone more underwhelmed at a question in my life. She moved very quickly on to the cast of Matilda, I’ll tell you that for free.”
Asked by presenter Susanna Reid if Kate listened to the podcast, ele respondeu: “If she does, she’s playing a very canny game of looking like she didn’t know what I was talking about.”
Kate has already made a parenting podcast debut, appearing on Happy Mum Happy Baby hosted by Giovanna Fletcher in 2020.
She confessed to struggling with “mummy guilt” and said she tried “hypnobirthing” when pregnant.
