Lindsay Lohan may have been treated for exhaustion Friday after working a whopping 85 hours in four days, but that didn't stop the Liz & Dick actress from partying in Hollywood Saturday night.
Spotted hanging at swanky L.A. hotspot Chateau Marmont Saturday, the 25-year-old appeared to have come straight from filming the Elizabeth Taylor biopic, with her brunette 'do and cat-eye makeup still in tact.
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 a.m.," an eyewitness told Us Weekly of Lohan, who stayed until Chateau's restaurant cleared out.
Update: Lohan's rep explains to Us Weekly of her late-night meal, "Lindsay had been working the night shift the last 2 or 3 nights so it's quite reasonable that she was up and having dinner at 1 am. She's working a shift from 8 pm to 9 am. It takes her body a day or two to adjust back from that timing. At 7:30 am on Monday morning, she was in the car and on her way to the set by 8 am."
On Friday afternoon, a false report circulated that Lohan had been found unconscious and was rushed to an L.A. hospital. After her rep, Steve Honig, denounced the claims, Lohan herself took to Twitter to assure fans that she was OK — just tired.
"Note to self.. After working 85 hours in 4 days, and being up all night shooting, be very aware that you might pass out from exhaustion & 7 paramedics MIGHT show up @ your door… Hopefully they're cute. Otherwise it would be a real let down," she wrote via Twitter early Saturday morning. "Back on set," she added.
Lohan's rep confirmed that the actress — shooting Lifetime's Liz & Dick opposite Grant Bowler in Marina del Ray, Calif. — indeed suffered exhaustion and dehydration, and tried to sneak in a nap on set when producers became concerned.
"She took a nap before shooting her scene," Honig explained. "Producers were concerned when she did not come out of her room and called paramedics as a precaution. Lindsay was never taken to a hospital. She was examined and is fine."
