"Jersey Shore" star Deena Nicole Cortese spent a few hours in jail yesterday -- after getting busted for disorderly conduct during a wild whirlwind around Seaside Heights.
Though the "meatball" was arrested after blocking traffic while dancing in the middle of the street, she was seen earlier in the day acting a fool all over the boardwalk.
In photos taken before her arrest, Deena can be seen dancing on bars and on the boardwalk by herself before playing arcade games collapsing next to a giant stuffed monkey.
The self-described "Blast in a Glass" may look like she's having a great time here ... but that look was definitely gone hours later when her parents came and busted her out of jail.
