Paramedics were called Friday to treat Lindsay Lohan after she was reportedly found non-responsive in the penthouse of the Ritz-Carlton hotel in Marina del Rey, Calif., TMZ reported.
Members of her entourage reportedly became concerned when they could not rouse her from her sleep at around 10:15am local time.
Paramedics arrived and determined that there was no cause for concern. Contrary to earlier local reports, she was not hospitalized.
The 25-year-old actress is in the area to film her starring role as Elizabeth Taylor in the Lifetime film "Liz & Dick."
TMZ reported that the actress is back at work on the set.
Last Friday, Lohan was hospitalized after her Porsche rear-ended an 18-wheeler on the Pacific Coast Highway in Los Angeles.
Though photos showed she suffered bruising after the accident, which totaled her car, her rep said she was not seriously injured.
