David Walliams wanted to write ‘evil’ Simon Cowell book

The 44-year-old said he thought he would write a book “about a record executive who’s on TV who doesn’t have a heart, he has a mechanical heart”.

He was responding to a question from a young boy in the audience at the Radio Times Festival, who asked if Walliams had ever considered writing about his and Cowell’s “romance”.

The author said: “I was a bit worried it would be the obvious choice. He would make a great villain because he is actually pure evil.”
