Playboy boss Hugh Hefner has brushed off an ex-girlfriend's critical tell-all book detailing life in his legendary Playboy Mansion, but admits he's disappointed by her actions. The 80-year-old tycoon has been blasted by resident lover-of-two-years IZABELLA ST JAMES, who claims girls suffer a 9pm curfew in the Los Angeles mansion and are only granted sex once a week. Her expose, titled BUNNY TALES, is set for release next month (AUG06) but Hefner is far from concerned. He tells, "What can I say? Some of them (the girlfriends) get a life (after their time at the mansion) and some of them write books. "I put her through law school, and I see she's choosing not to use it. I wish her well." Bunny Tales is the second book about Hefner's raunchy house - former Playmate JILL ANN SPAULDING described the place as a "brokerage house where dangerous sex is traded for stardom" in JILL ANN: UPSTAIRS.
