With less than a week to go until her court-ordered stint in rehab, Lindsay Lohan hit the NYC bar scene Monday night … and YES….SHE ACTUALLY BEHAVED HERSELF!!!

According to TMZ, Lohan spent her Monday evening at The Bitter End — the piano bar credited with giving Lady Gaga her start back in the day.


Sources at the bar tell us … Lohan rolled in to the place with 9 or 10 friends to watch some of her pals perform at a “Jam Fest” event.

Sources say Lindsay sat quietly at her table for roughly 3 hours and didn’t suck down one drop of alcohol — just soda (WOW).


One source inside the bar says she was so “very well behaved” … people in the joint barely even noticed the actress. (Seriously….shocking.)

As for Lindsay, she’s expected to enter a treatment center in the Hamptons on May 2 — where she’s supposed to complete a 90-day program.
