Unauthorised or unauthorized biography

Biography written without the subject's permission or input

"Tell-all" redirects here. For the novel, see Tell-All.

"Kiss-and-tell" redirects here. For other uses, see Kiss and Tell.

An unauthorized biography sometimes called a kiss-and-tell, or a tell-all, is a biography written without the subject's permission or input.

The term is usually restricted to biographies written within the subject's lifetime or shortly after their death; as such, it is not applied to biographies of historical figures written long after their deaths.

Objectivity

Unauthorized biographies may be considered more objective but less detailed than other biographies, because they are not subject to the subject's (subjective) approval (and therefore may contain accurate information that the subject would not have authorized), but are also not privy to information or corrections known only to the subject or the subject's close friends and family.
