Lindsay Lohan -- My Ass Says That Crappy Sofa's Gotta Go

Lindsay Lohan won't put her ass on just any piece of furniture ... that's why she packed up her crappy old sofa and banished it from her swanky NYC apartment.

A moving truck and crew pulled up to Lilo's chi-chi SoHo crib yesterday -- which led to speculation she was moving out -- but sources tell us they were simply there to load up the old couch and deliver a brand spankin' new one.

Sources say Lindsay's been living in the $16,000 a month pad while shooting her docu-series for Oprah Winfrey's cable network -- so the apartment doubles as a set for the show.
