11:43 AM PT -- Russillo drunkenly passed out in a stranger's bed ... cops say.
Long story short, cops were called to a home by the owner around 3:30 AM on Wednesday to report a strange man sleeping in one of the bedrooms.
When cops arrived, they found Russillo who appeared to be hammered out of his face -- "blood shot glassy eyes, very slurred speech and could not answer questions coherently, all signs of alcohol intoxication."
Cops say Russillo didn't know where he was or where he was supposed to be staying.
Officers also don't believe he forced entry -- and say he got in the house through a door that hadn't been secured properly.
