Paramedics were called early Friday after Lindsay Lohan was reported non-responsive at her Los Angeles hotel.
Sources tell TMZLindsay had been shooting her TV movie "Liz and Dick" almost non-stop for two days and was staying at the Ritz Carlton Hotel in Marina del Rey.
She has been shooting movie scenes near the hotel.
TMZ reports an employee of the hotel became alarmed because they could not wake her up, and the person called 911.
Paramedics came to the hotel, determined nothing was wrong with Lohan, and left without transporting her to the hospital, TMZ reports.
An LA Fire Dept. rep confirmed to Fox News that a woman in her 20s had been treated at the hotel's address, but would not release her identity. They said the individual was not taken to the hospital.
Lohan's father Michael Lohan told FoxNews.com that she was "fine" and that the situation had been "exaggerated."
Local station KABC said they have spoken to her attorney who also said Lohan is "fine."
