Los Angeles ? Anna Nicole Smith was “obsessed” with pills and was assisted in taking drugs by her lawyer-boyfriend in the weeks before her death, the celebrity model’s bodyguard testified Friday.

Maurice Brighthaupt depicted a chaotic situation at the home where Smith was staying in the Bahamas after the birth of her daughter and the death of her son, Daniel, from a drug overdose.

Brighthaupt said he saw defendant Howard K. Stern holding Smith’s head and giving her pills when she was too weak to take them on her own.

Meanwhile, Dr. Khristine Eroshevich, another defendant who was Smith’s psychiatrist, was trying to hide medications from Smith after shipping the drugs to the model from Los Angeles, he said.

Brighthaupt identified shipping receipts and said Eroshevich sent chloral hydrate, a powerful sleep medicine, which Smith gulped from the bottle. It was named in her autopsy as one of the nine drugs on which she eventually overdosed.

“She was demanding them like an addict,” Brighthaupt said, but the comment was stricken by the judge because an issue in the case is whether Smith was addicted or merely dependent on drugs to ease pain.

Stern and Eroshevich have pleaded not guilty along with Dr. Sandeep Kapoor to conspiring to supply the Playboy model and reality TV star with massive amounts of opiates and sleep medications. They are not charged with causing her 2007 overdose death in a Hollywood, Fla., hotel room.

On cross-examination by Stern’s lawyer, Steve Sadow, Brighthaupt said Stern loved and cared for Smith.
