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.

Most models lie about their age because they're too young, but not Agyness Deyn.
The British supermodel was signed by an agency at 23, but thought "that was quite old for a new face" so she "knocked a few years off". And by a few she means 6 years.
So how old is she?
Aggy was happy to admit to the UK's Guardian newspaper she turned 29 last week.
She still looks like a young 20 something to us.
