The day before, paramedics were called to Lindsay‘s hotel room as a precaution when producers were concerned that she didn’t show up for her final scene of the day.

“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….” Lindsay tweeted later in the day. “Hopefully theyre cute. Otherwise it would be a real let down. XL @mrsalperez -back on set”
