So what? The property's rent-controlled, and under local law someone benefitting from rent stabilisation needs to actually live for the majority of the time in the property. Her relationship with her landlords appears to have already been fractious, with a claim of unpaid rent back in 2009. How's it looking, according to the New York Times her New York neighbours claim to have never met her.
The property has a beach, a pool, even - bizarrely - it's own hairdressers. It's actually a rather sad story, of prescription pain killers, heart problems and a failing career.
