Paramedics were called early Friday after Lindsay Lohan was reported unresponsive at her Los Angeles hotel.
Sources tell TMZ Lindsay 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. 
"Liz and Dick" producers became alarmed when they called her room and she did not respond, and called 911.
Paramedics came to the hotel, determined nothing was wrong with Lohan, and left without transporting her to the
hospital.
"Lindsay worked a grueling schedule the past few days. She was on set last night at 7 pm and worked through the night until 8 am this morning. She took a nap before shooting her final scene," her rep Steve Honig told FoxNews.com.
"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 said. "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."
Lohan's father Michael Lohan also told FoxNews.com that she was "fine" and that the situation had been "exaggerated."
