lilopeaceparty230.jpgLindsay Lohan may be fresh from rehab and facing possible jail time, but rather than taking it easy, it sounds like the 24-year-old starlet is back to her hard partying habits!

A source tells X17online exclusively that after stopping by the SL Lounge in New York City last night, Lilo headed over to 1Oak and stayed until 4am! The insider added, "She is only doing this because she won't be photographed in NY like she is in LA, so she thinks she can get away with it. It certainly seems like she's fallen back to her old party habits, as evident from her wild behavior and the company she's keeping."

Apparently Lilo was tearing it up on the dance floor with a group of drunk men, and while she hasn't tweeted anything recently, we're curious to see what she has to say about this!

Interestingly enough, the last time she partied at 1Oak into the wee hours of the morning was in September, and just several days after that she failed one of her court mandated drug tests.
