A new unauthorized biography of Simon Cowell is about to be released, and it contains controversial information about the X-Factor judge.

According to reporters, the book contains details about the former American Idol judge’s affair with Dannii Minogue and his obsession with Botox, the anti-wrinkle drug.

In response, the 52-year-old has rejected the book’s claims, but the author—Tom Bower—insists that he and Cowell remain friends.

The publishing of the book will not be the last obstacle for their friendship (even if they get past it). Bower is already planning a sequel for the book.
