Anna Nicole Smith was addicted to prescription drugs and her psychiatrist should have known it, an expert witness told a Los Angeles court.

Defence lawyers in the drug case surrounding the death of Anna Nicole Smith have been notified that prosecutors will file an amended complaint at a discovery hearing today.

Anna Nicole Smith’s boyfriend Howard K. Stern and two doctors were charged with giving thousands of prescription drugs to the former Playboy playmate in the years leading up to her 2007 fatal overdose.
