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.

There's only one explanation for this matronly outfit: Big Sean's out of town!
With the rapper nowhere to be found, the Glee actress covered up her sizzling bod in a Carolina Herrera polka dot top with matching baggy, drawstring pants that were incredibly unflattering.
It also didn't help that Naya slicked back her hair, but we will say her dewy makeup looked superb!
Hopefully Big Sean will be back in town real soon; we're not sure we can handle another look like this!
