The 25-year-old, who blamed her hectic work schedule for her recent health scare, reached the club straight from the sets of her TV show 'Liz & Dick'.
Spotted hanging at LA hotspot Chateau Marmont, Lohan had her brunette do and cat-eye makeup still intact as she came straight from filming the Elizabeth Taylor biopic.
Chatting with a group of five men, Lohan spent the night surrounded by celebs including "Pretty Little Liars" Ashley Benson, Busy Philipps and Haylie Duff. "For someone so exhausted, it was shocking to see her out past 1 am," an eyewitness said.
