REVEALED: Jennifer Lopez, 32, is getting the Michael Jackson treatment in a sizzling British TV documentary set to air Wednesday with the title “Behind the Behind.” Airing on Britain’s Channel 4, the show disputes her “Jenny from the Block” image through interviews with early acquaintances who say the singer never spent much time in the Bronx because she was busy shopping downtown. “She’s another Hollywood star who’s forgotten where she comes from,” says family pal Henry Palayo. “She’s very artificial — more artificial than a plastic nose.” U.S. broadcast rights have yet to be picked up.

UNCOVERED: “Joe Millionaire” runner-up Sarah Kozer, 29, shows almost all in the new issue of Playboy, though she insisted that her photo spread include no full-frontal shots. “I was a women’s studies major,” she told the Associated Press Monday night, at a party celebrating her appearance in the publication. Since the show’s February finale, Kozer has been finishing a novel and a cookbook.

SALUTED: Fifty years after her Oscar-winning movie debut as the runaway princess in “Roman Holiday,” the late Audrey Hepburn is being honored in Rome with an exhibit of 130 posters and sketches from Italian publicity campaigns for her movies, which also include such classics as “Sabrina,” “My Fair Lady” and “Breakfast at Tiffany’s,” says AP. Proceeds will go toward the building of a school in the Horn of Africa, sponsored by UNICEF, for whom Hepburn was an ambassador from 1987 until her death in 1993 at age 63.
