Larry Birkhead takes stand again at Smith trial

Actress' ex scheduled to resume testimony Mon. in L.A.

The man who fathered Anna Nicole Smith's daughter is taking the witness stand again in the drug conspiracy trial of her boyfriend and doctors.

Larry Birkhead is scheduled to resume testimony Monday in Los Angeles. He told jurors last week that Smith suffered from seizures and other ailments. Birkhead also testified that he felt Smith exhibited loopy behavior during a 2004 awards show appearance and he felt that drugs were partly to blame.

Smith's boyfriend, Howard K. Stern, and two doctors have pleaded not guilty to conspiring to provide the former Playboy model with massive doses of opiates and sedatives.

They aren't accused of causing her 2007 overdose death.
