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.

The gown featured heavy fringe and beading, but the plunging back had heads turning.
Too bad she didn't wear a necklace! The look appears a little incomplete without some jewels, no??
But luckily she had a beautiful Judith Leiber clutch to keep her goodies in for the rest of the evening.
We're sure she and Muse hubby Matt Bellamy had a blast!!
What are U thinking??
