Lindsay Lohan admitted to working 85 hours in 4 days prior to last week's collapse.

Lindsay Lohan partied until the early hours just one day after being treated for exhaustion.

The 'Liz & Dick' actress went straight to the Chateau Marmont in Los Angeles on Saturday (06-16-12) after spending the day filming the TV biopic and didn't leave until after 1 am even though paramedics were called to her hotel room the day before when she passed out from exhaustion.

An eyewitness told US Weekly: ''For someone so exhausted, it was shocking to see her out past 1 a.m.''

Lindsay partied with 'Pretty Little Liars' actress Ashley Benson, Cougar Town's Busy Philipps and Haylie Duff, sister of her former arch rival Hilary Duff and a group of five men.

Lindsay, 25, was found ''unresponsive'' in the penthouse of the Ritz-Carlton in Marina del Rey, California on Friday morning (06-15-12) and was said to be suffering from exhaustion after working 85 hours in four days on the TV movie 'Liz &Dick'.

However, she played down the incident and even joked about it on twitter.

She wrote: ''Note to self.. After working 85 hours in 4 days, and being up all night shooting, be very aware that you might pass out from exhaustion & 7 paramedics MIGHT show up @ your door... Hopefully they're cute. Otherwise it would be a real let down.''
