While one would expect sexy details in a profile of Hugh Hefner, the interesting thing about Steven Watts’ new book is that most of his accounts are true.

To assist with Mr. Playboy: Hugh Hefner and the American Dream, The Girls Next Door star gave the author access to personal documents. As a result, the upcoming release is - in Hugh’s words - the “most authoritative book ever written” about him.

So what should curious readers come to expect from Mr. Playboy? The tales include an attempted wife-swapping with his Playboy co-founder, a sexual encounter with sister-in-law (with his brother’s permission), a “one-time homosexual experience” and a homemade porno. And that’s all probably in just Chapter One.

Well - if that proposed biopic ever gets off the ground, Robert Downey Jr. will probably have a lot of ground to cover!
