The thief who took the gown says he took the dress from Lupita's room at The London after finding the door ajar.

Because he was standing right behind that perfect booty!!!
Granted, it was covered up in a silver and sheer ensem that showed a peek of her taut abs and DEM LEGZ!
Not only did Iggy’s ensem fit in with the space theme of the night, but it made our jaws hit the floor!
