A businessman embroiled in a property dispute with Anna Nicole Smith said Thursday he wants to evict the reality TV star from the mansion where she has been secluded since her son's death in September.

South Carolina developer G. Ben Thompson, who says he is a former boyfriend of Smith, told reporters that he loaned her money to buy the waterfront mansion for nearly $1 million, but she has failed to make payments on the mortgage.

Smith, a former Playboy Playmate, has cited ownership of the home as the basis of her claim of residency in the Bahamas, where she came to give birth to a daughter. Her 20-year-old son, Daniel, died under mysterious circumstances at the hospital three days after she gave birth.

Thompson said at a news conference in Nassau that he met Smith about 18 months ago and they had a "short relationship." He said they remained friendly until the dispute over the house in an exclusive neighborhood on the eastern end of New Providence island.

"I'm shocked and appalled at what she's done," he said.

Thompson, of Myrtle Beach, said Smith told him that he was the father of her new daughter, Dannielynn. The developer, however, told reporters that he's certain he is not the father.

He also said he and his family had also provided money for expenses such as security, maid service and utilities.

"She doesn't have a penny in that house," Thompson said.

Smith has publicly identified Dannielynn's father as her attorney and confidant, Howard K. Stern. But photographer Larry Birkhead claims he is the father and has filed a lawsuit demanding that Smith and the child come to California to establish paternity through DNA tests.

Smith, who was hospitalized Monday with pneumonia and received treatment for a partially collapsed lung, said in an interview set to air Thursday night on TV shows "Entertainment Tonight" and "The Insider" that the death of her son was painful.

"I'll never, I'll never, I'll never accept that he's gone," Smith said. "I don't know why God took him and didn't take me."

She added: "If I didn't have Howard or my baby, I wouldn't be here."

Doctors in Nassau were keeping Smith at the hospital Thursday out of "an abundance of caution" because she recently gave birth, said her attorney Wayne Munroe.

Daniel Smith died Sept. 10 in his mother's room at Doctors Hospital in Nassau. The results of official toxicology tests and a police investigation have not been released.

A private examiner hired by the family, Cyril Wecht, said Smith died from a lethal combination of methadone and the antidepressants Zoloft and Lexapro. Wecht also detected trace amounts of a third antidepressant, Amitryptiline, two over-the-counter cold medicines and the sleep medication Ambien in Daniel's system, but said they did not contribute to his death.
