Lydia Hearst's Page Six Costume PWNED by BritneyLydia's Halloween costume is what's killing print. The publishing heiress and model referenced her recent little scandal of quitting her "column" in Page Six magazine by dressing up as the tabloid for a party last night. Cute, Lydia—but Britney Spears wore this exact same costume years and years ago:Update: "I am Lydia's PR. don't you get it? She is being Britany !!!! that was her costume? can't you tell that they are wearing the same outfit? Duh Gawker!!!!" (When we finally get the juice to hire a PRgay, we're gonna go with one who uses periods and questions marks properly?)
