The beleaguered starlet has been fighting a losing battle with substance abuse since 2007, but her strange behavior isn’t easily blamed on just the drugs. She’s an absolute nightmare behind the wheel, she allegedly slugged a woman in a NYC nightclub last fall, and then to round out the wacko rap sheet, there’s that one time in 2007 that she allegedly “chased and threatened” her then personal-assistant’s mother around a Santa Monica parking lot. As the recent NYT profile suggests, this is not a woman you want on your set if you can help it.
