Brigitte Nielsen fell asleep in a Los Angeles park after going on a drinking binge on Saturday August 4, 2012.
The Danish actress - who has previously entered rehab in 2007 for alcohol issues - swigged from a vodka bottle and chain smoked cigarettes while sitting alone on a park bench, before appearing to take a nap.
The 49-year-old star also appeared to vomit before using mouthwash to freshen her breath before walking back to her house in Hollywood.
An onlooker told the Daily Star newspaper: "It was sad to see her brought so low. She needs help."
Speaking previously about her battle with booze, Brigitte - who was previously married to Sylvester Stallone and is currently with Mattia Dessi, her fifth husband - said alcohol turned her into an "ugly" person.
She said: "Booze turned me into a bad mom, an ugly, depressed woman and a complete loser. I heard voices in my head telling me to drink. I even drank just to pick up the phone because I felt such self-loathing and embarrassment."
In recent years she has been best known for her reality TV career, appearing in Danish 'Big Brother VIP', British show 'Celebrity Big Brother' and 'Celebrity Rehab with Dr Drew'.
