Lohan's publicist Steve Honig says producers of the Lifetime film "Liz and Dick" summoned paramedics to Lohan's hotel room Friday morning after she did not respond for a shoot. The incident occurred after the actress completed an all-night shoot and had kept up a grueling schedule in recent days, Honig said.
The actress was not transported to the hospital and will likely return to the set of the film Friday afternoon. The film focuses on the love affair between Elizabeth Taylor and Richard Burton.
Lifetime declined comment. And it was unclear whether the incident led to any delay in the film's production.
Fire officials confirmed they were summoned to a hotel in Marina del Rey on Friday morning around 10:15 a.m., but said they did not transport anyone to the hospital. They also said they could not identify the patient.
The incident is the latest scare for Lohan, who was involved in a car crash June 8 that sent her and her assistant to a hospital. The pair were on the way to a "Liz and Dick" shoot when the Porsche they were in collided with a dump truck on the Pacific Coast Highway. Neither was seriously injured and Lohan resumed shooting later in the day.
The accident remains under investigation and police have said they are still trying to determine who was driving.
Lohan, 25, remains on informal probation for taking a necklace last year from a jewelry store without permission. She is not required to check in with a judge or probation officer, but could face a jail term if she is re-arrested.
