Lindsay Lohan's increasingly erratic behavior has friends worried about her life. TMZ quotes someone it describes as "extremely close" to her as saying, "If she doesn't get help soon, she's going to die." Friends are pushing her to get back into rehab for substance abuse, but Lohan is refusing to acknowledge the problem. When she fell recently in public (see summary here), she blamed paparazzi for pushing her. (More Lindsay Lohan stories.)
