As part of an expose on why Denise Richards doesn't want estranged husband Charlie Sheen to have visiting rights with their children, In Touch interviews Heidi Fleiss, the Hollywood Madame. Of a report that Charlie spent more than $50,000 on Heidi's whores in 1992 and 93 she says "The guy's a rat! Of course it's true. It's totally normal behavior for him." Fleiss, who is planning to open Heidi Fleiss's Paradise in Nevada, should consider keeping her trap shut. Who wants to play with the girl scouts if the den mother tells all afterwards? (By Scott Rose)
