She told the BBC Radio 2 show ahead of the book’s release that her father was a “complex man” who struggled with mental health issues and periods of homelessness.

Bilton told the show that her brief relationship with her half-brother after graduation “is what happens when sperm donation isn’t regulated and you have a lot of half-siblings.”

“I invited them all to visit me at my house and my attitude towards that has changed — now I see them as this extended biological family.”
