AceShowbiz - Anna Nicole Smith's ex-lover Larry Birkhead fought back tears in court on Friday, August 20 as he testified about the late star's drug lows. The photographer, who is the father of Smith's daughter Dannielynn, resumed testifying in the drug conspiracy trial of doctors Khristine Eroshevich and Sandeep Kapoor and Smith's former boyfriend and lawyer Howard K. Stern and told the court in Los Angeles that the actress/model often suffered seizures after taking drugs.

Birkhead also revealed Anna Nicole would fall asleep during meals because of the numerous prescription medications she was taking. The doctors and Stern are accused of prescribing to an addict, as well as conspiring to provide excessive opiates and sedatives to Smith. All three have pleaded not guilty to conspiracy to provide excessive drugs to the star.

Birkhead, who once battled Stern for custody of Dannielynn and has recently become the lawyer's friend, said he saw Stern give Smith medicine when she didn't feel well, and testified he knew the attorney was picking up prescriptions for her. And when he hid a powerful painkiller from his then-girlfriend, Stern called him and asked where it was.

But Anna Nicole always insisted she was not an addict, despite the large amounts of drugs she took for a number of ailments. Birkhead revealed, "She would say, 'I'm in pain. I'm not a drug addict... I have a high tolerance because I'm in pain'."

The three-week-old trial continues.
