LINDSAY Lohan may have been treated for exhaustion on Friday, but it reportedly didn't stop her partying late Saturday night.

The troubled starlet, who said she collapsed and was treated by paramedics after working 85 hours in four days, was spotted partying at West Hollywood's Chateau Marmont on Saturday, according to Us Weekly.

Lohan, who is filming the Elizabeth Taylor biopic Liz and Dick, was spotted with the icon's dark-haired 'do and cat-eyes makeup still intact.

The magazine reported that Lohan was surrounded by celebrities including Busy Philipps and Haylie Duff and quoted a source as saying, "For someone so exhausted, it was shocking to see her out post-1am ."

After she collapsed on Friday, Lohan tweeted, "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."

Her rep, Steve Honig, explained she was suffering from exhaustion and dehydration and had tried to take a nap before producers became concerned.

"Producers ... called paramedics as a precaution. Lindsay was never taken to hospital. She was examined and is fine," Honig said.
