Lindsay Lohan did her due diligence in showing up to her DUI classes Wednesday afternoon; by Wednesday evening and into the wee hours of Thursday morning, she was back to painting the town red, as RadarOnline.com has obtained pics of the Mean Girls star leaving Las Palmas Night Club in Hollywood.
Earlier in the day, Lohan said she would be "supporting a friend" associated with the club by fitting the Las Palmas staff with selections from her 6126 clothing line.
"We're actually dressing all the staff and the waitresses, which is really exciting," Lohan said. "I'm supporting a friend, so off to work -- work, work, work, work, work!"
After leaving the club around 2:15 a.m., Lohan then attended a house party in the Hollywood Hills until 5 a.m.
Lohan, 23, will be back in court for a progress report on her DUI classes on May 20.
