Paramedics rushed to Lindsay Lohan early today after she was found non-responsive at a hotel by the ocean in L.A.
Sources tell TMZ ... Lindsay had been shooting almost non-stop -- without sleep -- for 2 days and was staying at the Ritz Carlton Hotel in Marina del Rey to get some sleep. She has been shooting parts of her movie near the hotel.
We're told someone became alarmed because they could not wake her up and the person called 911.
Paramedics responded, and determined nothing was wrong with Lindsay. They left without transporting her to the hospital.
Lindsay is back on set shooting her Lifetime movie, "Liz and Dick."
As far as we know, Lindsay did not go to the hospital herself.
