Well, the dress has been found ... to be a fake!
The thief who took the gown says he took the dress from Lupita's room at The London after finding the door ajar.

It was a bit nipply in New York City on Monday, at least that's what we're gathering by Rihanna's personal thermometers!
The songstress left little to the imagination while out and about in the concrete jungle in a lacy Topshop bandeau top with matching pleated skirt.
RiRi also rocked a pair of Karen Walker hater blockers and a mini Celine bag.
The look is cute, but she really should invest in some bras. You work with Armani, gurl! We know you can get some for free!
