The "Mean Girls" star - who recently completed a stint in rehab for alcoholism - claims she parties all night, despite the temptation to drink, because she hates going to bed alone.

Lindsay, who is rumored to be involved in a lesbian relationship with DJ friend Samantha Ronson, told Nylon magazine: "It's so much harder to stay sober in New York."

"Though it's hard in Los Angeles not to go out, it gets lonely. Being an actress is lonely, and I never want to be alone. I hate sleeping alone."

The 20-year-old - who last year was sent a warning letter from movie producers of her film "Georgia Rule" scolding her for her continuous partying and apparent lack of professionalism - believes she deserves to go out and have fun as she works so hard.

Lindsay, who was accompanied by Ronson throughout the interview, said: "I'm at the point where I think 'Oh my God I'm going to go out!'"

"I work hard enough and I know how to take care of myself. I don't know what's going to happen tomorrow."
