Not even treatment for exhaustion Friday could keep Lindsay Lohan from partying it up on Saturday night, reports Us Weekly.

The 25-year-old actress is back up and running and was spotted partying at the Chateau Marmont until 1 a.m., according to eyewitnesses who told the magazine Lohan was among the last to leave the Chateau's restaurant.

The actress made a speedy recovery after being found non-responsive in her hotel room on June 15. Paramedics rushed to the penthouse of the Ritz-Carlton in Marina del Rey and treated Lohan for dehydration and exhaustion.

On Saturday morning Lohan spoke out about her health scare via Twitter, citing long hours of filming the upcoming Elizabeth Taylor biopic, "Liz & Dick," for causing her exhaustive state.

"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," Lohan tweeted.

Lohan's rep, Steve Honig, also released a statement to the press Saturday, blaming the actress's "grueling schedule" for the incident:

"[Lindsay] was on set last night at 7 pm and worked through the night until 8 am this morning. She took a nap before shooting her final scene. Producers were concerned when she did not come out of her room and called paramedics as a precaution," said Honig. "Lindsay was examined and is fine, but did suffer some exhaustion and dehydration. Lindsay was never taken to a hospital; reports to the contrary are false. She is resting now and is hoping to be back on set later this afternoon."
