Paris Hilton -- Smell Me, I'm Famous [CREEPY VIDEO]

Paris Hilton needs someone to watch her back ... because when no one's looking some random dude is smelling her hair.

Paris was leaving Dan Tana's restaurant in West Hollywood -- celebrating her 33rd birthday with her parents -- when a bald guy in a Burberry shirt brings up the rear and cranes his neck for a whiff of her locks.

Paris has had trouble recently with obsessed fans and stalkers ... mostly recently a dude from Germany who landed at LAX and beelined it for her Estate and told the guard at the gate he was in love with Paris and had to see her.  He was arrested ... but plenty of weirdos out there.
