Prue Leith asked Sandi Toksvig's wife for lesbian sex scene tips for her new book.
The 'Great British Bake Off' judge turned to the show's co-host's partner Debbie to help as a consultant on the racy scenes featured in her latest novel 'The Lost Son', and has thanked her for having "approved my chapters on a lesbian love affair".
According to the Daily Mirror newspaper, Prue joked in the acknowledgements: "Looking at the list you could be forgiven for thinking that I knew very little about anything.
"But at least the story is my own, and I know it's the better for the help of my friends."
It's said that one of the saucy extracts includes a detailed shower scene with two characters soaping each other up, before drying each other "feverishly".
As the narrator, the 79-year-old author describes it as "the sexiest thing they had done", and it appears Sandi's psychotherapist wife provided some insight into the raunchy moments.
The loved-up couple joined in a civil partnership back in 2007, and they later renewed their vows on March 29, 2014 - which was the day same-sex marriage was legalised in England and Wales.
In December that year, their civil partnership was turned into a marriage.
Prue previously revealed the awkward moment she accidentally stabbed a colleague in his leg - but she initially feared it was his "manhood".
She recently explained: "I once thought I'd stabbed a fellow chef in the manhood.
"I was very pregnant and quite unbalanced, and I slipped and fell with a knife in my hand and blood poured out of his upper thigh."
