What is it with One Brooklyn Bridge Park? A tipster says three celebrities are checking out the luxe 449-unit condo project, whose former incarnation was headquarters for the decidedly un-luxe Watchtower, a magazine published by the Jehovah's Witness. Model Bridget Hall was recently spotted at the building, presumably for a tour, as has another catwalker, now turned reality-TV-and-talk-show host Tyra Banks. Hilary Swank is said to be interested in the property, too, and is apparently expected for a look-see soon. According to the Brooklyn Eagle, the building's transformation has piqued such interest that its waiting list of potential buyers was 3000 strong earlier this year. Real-estate doyenne Elizabeth Stribling bought two units there, and now her posh brokerage firm, Stribling & Associates, helps market the project. —S. Jhoanna Robledo
