Amanda Bynes puffed a Camel cigarette on the streets of NYC Friday evening ... then rolled into the Cartier store wearing sweatpants ... and the situation continues to be desperate with no happy resolution.
Bynes -- sporting a bandage under her eye -- walked around the Upper East Side Friday before hitting up the fancy jewelry store.
Doesn't look like she bought anything ... as she left the store, undercover.
We spoke with multiple people who saw Amanda in Union Square last night as well ... and they say she seemed very paranoid. They also tell us she was speaking to inanimate objects like a tree.
As we previously reported, Bynes was acting very strange at LAX before her flight to NYC -- and people close to her feel the situation is dire. Until Amanda's parents pull the trigger and go back to court for a conservatorship, it's a waiting game until she poses a significant danger to herself or others.
