Hollywood Pin-Up Angelyne Faceplants Hard in Bev Hills [VIDEO]

Hollywood pin-up legend Angelyne -- known as the original Paris Hilton (famous for being famous) -- has finally hit rock bottom ... tripping and falling HARD in Beverly Hills on Friday.

Don't worry ... she didn't appear to be injured -- and she actually looked pretty good for a person who just face-planted in front of the paparazzi.

And just in case you're thinking to yourself -- "Who the hell is Angelyne?" ... she was a fame-whoring, attention-starved socialite who got sorta famous back in the '80s for putting up a bunch of billboards of herself all over L.A.. 

She's not really a model ... or an actress ... and no one knows her real age ... but we do know she's a real trip.
