The Mean Girls actress reportedly arrived around 11:00pm and appeared to be drinking non-alcoholic sodas throughout the night.  Lohan, who stumbled out of the nightclub due to an overwhelming amount of paparazzi flashes, left around 2:00am on Thursday.  The party didn't end there though!  Lohan and Hirsch were also spotted hitting up her favorite old stomping grounds, Chateau Marmont later that night.

Lindsay's mother Dina told the NY Daily News that she will be planning a "low key" celebration in Los Angeles for her 25th birthday, and "she plans to return to her community service right away on Monday."  Dina added, "Hopefully she'll get back to New York soon to celebrate with her grandmother, who's 85 and doesn't really like to fly. But there's no party in the Hamptons."

What do you guys think?  Should Lindsay Lohan really be out partying?!
