LiLo Explains Source of 'Exhaustion'

911 paramedics paid Lindsay Lohan a visit yesterday, and we're sure you breathed a huge sigh of relief when it turned out the currently employed actress was a-OK. Her rep explained that "exhaustion and dehydration" brought on by her tough work schedule were to blame. Lohan herself provided some additional details early today, tweeting, "Note to self.. After working 85hours in 4days, and being up all night shooting, be very aware that you might pass out from exhaustion & 7 paramedics MIGHT show up @ your door.... Hopefully theyre cute. Otherwise it would be a real let down. XL @mrsalperez -back on set."

Quips Gawker, "Wow, seven cute paramedics. That must have been some nap, huh?" Newser whipped out the calculator to helpfully let you know that by LiLo's math, she's gotten 2 hours and 45 minutes of sleep a day for the last four days. Click for more on the drama. (More celebrity stories.)
