The son of former reality TV star Anna Nicole Smith was laid to rest in Nassau yesterday as his distraught mother shouted "I'm sorry, I'm sorry" over his coffin, according to a witness.About 50 people, mainly family and friends, were at the ceremony at Lakeview Cemetery.

Anna Nicole's lawyer-boyfriend Howard Stern was among mourners and a nanny carried their five-week-old daughter, Dannie Lynn Hope.

Smith, 39, wearing a black dress and matching hat, was "visibly distressed", onlooker Felipe Major said.

Daniel Smith, 20, was found dead at his mother's bedside at Doctors Hospital in Nassau on September 10 when he was visiting his mother and baby sister, who was born three days before.

For five weeks, his body was kept in a Nassau morgue amid mounting concern over the length of time police were taking to complete investigations into the cause of death. Chief magistrate Roger Gomez said this week that he was awaiting a police report and the result of toxicology tests before deciding whether an inquest should proceed.

American pathologist Dr. Cyril Wecht, who reviewed the autopsy results at the family's request, disclosed three weeks ago that Daniel almost certainly died from a lethal drug cocktail, after methadone and two anti-depressants were found in his body.

The "acute toxicity" of the mixture would have affected the brain and lungs and compromised the heart, Wecht said, adding that the drugs could have been taken accidentally.

Anna Nicole Smith was Playboy's Playmate of the Year in 1993. She starred in a short-lived cable television reality series, The Anna Nicole Show<$>, from 2002 to 2004.
