• ... It's easy to vie for Fashion Week's social ubiquity crown when you don't really have a job. Unemployed actress Mischa Barton and accomplished devirginizer Jared Leto are in a dead heat heading into Fashion Week's final stretch. While most stars try to limit their exposure to create a sense of scarcity, Barton is actively courting the paps, seemingly counting on continuous press coverage to ease her transition from OC starlet to movie star. In her quest to conquer, Mischa has stepped out (in multiple costume changes) at Fashion Rocks, Milla Jovovich's Jovovich Hawk party, Marc Jacobs, Nanette Lepore, Marchesa, Anna Sui, and last night's The Black Dahlia premiere, where she arrived on the arm of designer Matthew Williamson. Is it working? At a backstage photo-op, one photographer was overheard telling another, "That's Marissa Bristow. She's on TV."

• ... Leto meanwhile, with his kohl-rimmed eyes and mini entourage, has been hitting every party on the Fashion Week circuit, from Baby Phat at Butter and the Purple Magazine Dinner, to Marc Jacobs, TAG Heuer, and last night's Diesel event. Having promised the press that his new tour will "blow people's eyelids off," the wee 30 Seconds to Mars frontman has also been flashing his bedroom eyes at just about every questionably-legal Eastern European model in town, reserving his best game for the prime late-night hunting grounds of Bungalow 8.

• ... Paris Hilton has been having a bad week. She was reportedly turned away from a party at Jovovich's townhouse by the model herself, who told the celebutard that the festivities had ended. Later in the week, she was rejected trying to crash Marc Jacobs. Word has it she's been all but banned from Ian Schrager's Gramercy Park Hotel, too. What, nobody wants to play with P?
