Lindsay Lohan Falls Down -- On Bended Knee

UPDATE: Lindsay just tweeted, "Is it not allowed to slip and fall? im always a klutz!!!"

Lindsay Lohan
was brought to her knees last night ... but in a bad way.

Lindsay took a spill on the streets of New York City -- on the Lower East Side -- after leaving the hipster dive, Motor City Bar.

That Red Bull really packs a punch.
