Lindsay Lohan racked up a massive $925,000 bill while staying at Hollywood's most expensive hotel.

The 19-year-old star reserved a luxurious bungalow at the Chateau Marmont Hotel - for most of last year.

But after splashing out to reserve the suite it appears Lindsay barely even visited Los Angeles in 2005.

A source said: "She tries to keep the bungalow reserved on the off chance she'll pop into LA."

"But it's a real waste of time and money."

The huge bill for the "Mean Girls" actress - who earns a reputed $7 million a film - doesn't even take into account extras such as Cristal champagne, at $555 a bottle, and the hotel's personal chauffeur, which costs guests $703 a day.

Lindsay has also been treating friends to meals and drinks and slapping them on her ever growing hotel tab.

Her accountants were furious when the actress handed them her bills and appeared unaware of how much money she was spending.

Another source revealed: "Her accountants were disgusted because she didn't realize she'd racked up such a huge bill."
