tweeted a reminder to herself today, hours after paramedics were called to the starlet's Marina del Ray, Calif., penthouse by producers of her new movie, "Liz and Dick," who feared the actress was unconscious after she did not come out of her room as scheduled.
"Note to self…after working 85hours in 4days, and being up all night shooting, be very aware that you might pass out from exhaustion + 7 paramedics MIGHT show up @ your door…Hopefully theyre cute. Otherwise it would be a real let down," @lindsaylohan tweeted.
Lohan's rep, Steve Honig, said the actress was asleep when the call was made. He blamed her inability to wake up on exhaustion and dehydration from long days on set.
"She was on set last night at 7 p.m. and worked through the night until 8 a.m. this morning," he said. "She took a nap before shooting her final scene. Producers were concerned when she did not come out of her room and called paramedics as a precaution. Lindsay was examined and is fine, but did suffer some exhaustion and dehydration."
Honig added, "Lindsay was never taken to a hospital; reports to the contrary are false. She is resting now and is hoping to be back on set later this afternoon."
The Los Angeles County Sheriff's office described Lohan's condition as "groggy" and said she's "OK as far as we know."
Lohan has been to rehab multiple times for drug and alcohol abuse. In March, she was taken off probation from her 2007 DUI case.
The actress has had a rough run of late. Last week, she totaled her Porsche by driving it into a dump truck on the Pacific Coast Highway.
