Just a few years ago, Lindsay Lohan was the hottest young actress in Hollywood, making the rarely successful transition from adorable child actor in "Parent Trap" and "Freaky Friday" to a bankable, A-list movie star.
When she posed as Marilyn Monroe for New York magazine in 2008, Lindsay seemed destined to follow her idol and become one of Hollywood's leading ladies for years to come.
Since then, however, her life has spiraled out of control. Several arrests and stints in rehab have put the actress on the covers of the celebrity tabloids. Now friends tell FOX411.com exclusively that Lohan, 23, is living in squalor, and she can't get a part in a movie because no one will insure her.
"Lindsay has been living in a major mess lately. Whether she's in her home or a hotel room, she does not pick up after herself or take care of things," a source close to Lindsay tells FOX411. "She sleeps on a mattress on the floor, there's spilled coffee and drinks around the rooms, and stuff all over, clothes everywhere. It is not a clean home environment. She sleeps most days and it is difficult to wake her up."
