After his rather flatulent appearance on the television show last summer, he's now hurling himself in the direction of the literary world with his new novel, entitled Essex, Drugs & Rock 'n' Roll.
Jane Austen territory this is not. It's about a wealthy, middle-aged man with family problems, who explores the darker side of life.
Diary anticipates those distinctly Durdenesque themes of cocaine- snorting and prostitution will crop up between the covers. All the ingredients of a sure-fire hit, then.
Except, his publishers are insisting that Durden's Big Brother appearance is his major selling-point, and, much to the media tycoon's horror, they are insisting that the cover of the book is revised so that it carries the immortal words "by Big Brother 8 contestant Jonathan Durden".
Copies of the book are available to pre-order on Amazon.co.uk.
