"I'm afraid that – I'm afraid he's stuck," she told Entertainment Tonight. "I'm afraid that he doesn't know where to go. I don't have anybody that's dead that he can go to. He doesn't know anybody. I'm afraid. We were so close that he doesn't want to leave me. I'm just afraid he's stuck."
Smith remained hospitalized Friday as she had fluid drained from a partially collapsed lung while recovering from pneumonia, her attorney said.
"She's doing a lot better, but when you would have a collapsed lung, they would keep you in," attorney Wayne Munroe told The Associated Press.
The former Playboy playmate on Monday checked into Doctors Hospital, the same facility where she gave birth to a daughter on Sept. 7 and her son died while visiting her three days later.
A private examiner said the cause of Daniel Smith's death was a lethal combination of methadone and antidepressants.
In Friday's Entertainment Tonight interview, Smith explained why her son had been taking anti-depressants at the time of his death.
"He was seeing a girl, and he was having problems, they were having problems," she said. She added that she was surprised the relationship had taken that kind of toll on him.
The results of official toxicology tests and a police investigation into his death have not been released.
Munroe said his client was not surprised by a South Carolina developer's assertion Thursday that he loaned her money for the gated, waterfront mansion where she has been living. G. Ben Thompson told reporters in Nassau he wanted to evict her because she has not honored an agreement to pay the mortgage.
