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.

What are friends for?!
The couple looked their usual selves, with Jason dressed down and Rosie looking like she's ready to hit the town.
The supermodel slash actress wore a simple tee and jeans combo, but spruced it up with a print Isabel Marant jacket and booties.
She’s always so cute, we just wish Jason cared as much about his clothes!
