Kristin Davis, the madam with the (allegedly) biggest black book in America, says she'll write a tell-all about the "naughty exploits" of the powerful and famous. Davis ran Wicked Models from a Murray Hill apartment and reportedly had over 10,000 clients. And in a nod to the actress with a similar name, the Daily News reports the book will be named "The Real Sex in the City: True Tales of the Manhattan Madam." Davis, who pleaded guilty to prostitution last week, also made this statement, "While it is true that Spitzer, as well as many other celebrities, patronized women employed by my former agencies, what is not accurate are the rumors that I personally serviced Spitzer."
