Arquette in Playboy: Actress Rosanna Arquette will be the subject of a 12-page nude spread in the September issue of Playboy magazine, and she isn't pleased about it. Arquette, probably best known for her role in "Desperately Seeking Susan," was on a swimsuit shoot for Conde Nast Traveler magazine in Naples, Fla., when she started taking off her clothes, which captured the attention of longtime celebrity photographer Bert Stern. Playboy spokesman Bill Farley said Arquette signed a release with Stern, stipulating only that the photos not be published in Britain, where her boyfriend, rock musician Peter Gabriel, lives. Stern put the pictures on the market and Playboy, unbeknown to Arquette, grabbed them. Arquette's spokesmen were in conference Wednesday and unavailable for comment.
