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.

And we certainly hope she wasn't playing it safe with the fashion tape, either!!
The British songstress opted for an Old Hollywood vibe with her black gown and sparkling, black clutch, putting most of the attention on that eye-popping cleave.
She even styled her gorge ensem with flawless waves and her signature red pout.
All around fabby!!
