UK female actress Billie Piper is to meet the real-life prostitute who inspired her role in Secret Diary of a Call Girl.
Dr Brooke Magnanti ended years of speculation by outing herself as the real Belle de Jour last month.
Her blogs and books inspired the ITV2 drama starring Billie Piper.
Billie Piper told TV Biz: "I have always been fascinated by the real Belle de Jour and I read everything about Brooke when she decided to 'come out'.
"It will be so interesting to meet her. I think everyone's fascinated to a certain degree about prostitution."
Their real-life encounter will be filmed for a documentary, Billie and the Call Girl Bare All, to be shown on ITV2 in the New Year.
Dr Magnanti said the programme would provide an insight into the "real woman" behind the alter ego.
It will be "the last world on what it was like to be Belle - how my sexuality was formed, how I came to the work and what it's like to be portrayed on TV", she said.
After outing herself because she feared a former boyfriend was about to disclose her identity to a newspaper, Dr Magnanti said she had no regrets about becoming a call girl.
It later emerged that her first encounter with prostitution was via her father, who admitted he had paid for sex with more than 150 women and introduced some of them to his daughter.
Diana Howie, ITV commissioning editor, said: "We're delighted that Billie and Brooke have agreed to make this programme. There are no two people better placed to bring to life this extraordinary story."
