Over two years since Anna Nicole Smith tragically died from a drug overdose, her former boyfriend and lawyer, Howard K. Stern, and two other doctors have been charged Thursday with conspiring to give her prescription drugs.

Stern, who was Smith's longtime partner, and even claimed to be the father of her baby girl, and doctors Sandeep Kapoor and Khristine Eroshevich were each charged with felony counts of conspiracy to "commit the crimes of prescribing, administering and dispensing controlled substances to an addict" and "unlawfully prescribing a controlled substance," the offices of the California attorney general and Los Angeles County district attorney announced.

The two doctors gave the drugs –including opiates and benzodiazepines – to the former Playboy playmate's boyfriend who then gave them to Smith over three years prior to her 2007 fatal overdose.

"These individuals repeatedly and excessively furnished thousands of prescription pills to Anna Nicole Smith, often for no legitimate medical purpose," California Attorney General Edmund G. Brown said in a statement.

The doctors and Stern were using fake names so that Smith could be prescribed thousands of pills, "She was obviously addicted," Brown added. "These doctors had a medical obligation to prescribe medicine in a professional way. Evidence will show this did not happen."

Two of the three have already been arrested, including Stern who turned himself in. He was arrested and booked by police in Whittier, Calif., with bail set for $20,000, police records show.

For six months prior to her death, Khristine Eroshevich, a licensed psychiatrist who practices in Anaheim and Los Angeles, treated the 39-year-old reality TV star following the death of her son, Daniel.

At the time of her death, Anna Nicole Smith's hotel room was packed with prescription medications. More than 600 pills - including about 450 muscle relaxants - were missing from prescriptions that were no more than five weeks old. Most of the drugs were prescribed in the name of Stern, her lawyer-turned-companion, and other fake names. None was prescribed in Smith's own name.
