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.

Not your typical frou-frou prom dress!
Madonna's firstborn is all grown-up and attended her senior prom for La Guardia High School on Saturday!
The simple number featured beautiful lace trim along the neckline and hem, and fit Lola perfectly! With her red lipstick and dark hair, she looked like she'd just stepped out of a Dolce & Gabbana ad!
Awww! We remember when Lola was just a baby!
Time doesn't just fly; it steamrolls you!
