Lindsay Lohan broke

Lindsay Lohan is reportedly broke after spending her $7 million fortune on drugs and alcohol.

The troubled Hollywood star - who left Utah's Cirque Lodge rehab clinic earlier this month after a two-month stay - is staying with movie producer Tom Gores in Los Angeles because her money has run out.

Gores was the executive producer of the 21-year-old actress' recent flop film 'I Know Who Killed Me'.

A source told Britain's News of the World newspaper: "Lindsay doesn't have much choice as she is totally broke. The only reason she's coming back to Los Angeles is to try and get some film work and earn some money fast.

"The amount she has wasted putting cocaine up her nose is disgusting. Even she has lost count."

Lindsay's extravagant spending spree reportedly includes $1 million on just one hotel bill.

She has also spent more than $137,000 on three separate stints in rehab battling her drug and alcohol addictions, and thousands more in legal fees after her conviction for DUI (driving under the influence).

Lindsay is also thought to have blown more than $1 million on clothes and $500,000 on partying, with another $70,000 spent in tanning and hair salons.

She has been forced her to sell her $2.85 million apartment in Los Angeles and her $1 million New York property because she couldn't afford the mortgage payments.

Last week, Lindsay's father Michael claimed she planned to stay away from Hollywood to avoid temptation.

He said: "She told me, 'Dad, I don't feel ready to go back to Hollywood.'

"That's how committed Lindsay is to her sobriety. She doesn't want to do anything to mess it up."
