Congrats to Deena Cortese -- her mug shot is an instant classic, 'cause the "Jersey Shore" star is sporting a look that screams WASTED.
TMZ obtained the mug shot taken last weekend by Seaside Heights PD after her arrest for disorderly conduct.
As TMZ first reported, Deena was busted on Sunday when she was dancing in the street outside a Mexican restaurant ... and drawing huge crowds of fans. Deena's parents bailed her out of jail later that day.
Her arraignment is scheduled for July 3.
