UPDATE

TMZ is reporting: We have more specifics.  We're told Lindsay wasn't feeling well after complaining of exhaustion, she called someone from the "Liz and Dick" production team early this morning, and the team sent a private doctor to check on her.  Before arriving, the doctor called the hotel and asked someone to check on Lindsay.  Someone from the hotel went to her door, "checked on her" and determined she was "unresponsive."  The hotel then called 911.

Lindsay's rep says it was someone from the production team who called 911.

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 shut eye.  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.
