IT'S NOT DIFFICULT to believe that

Madonna

may again take the adoption route to motherhood, but it is a little difficult to believe that she wants to try parenthood with boy toy

Jesus Luz

.

He's 22. She's 50. Why doesn't she just adopt him? Britain's News of the World reports that Madonna has switched her adoption efforts from Malawi to Nigeria, and that she hopes that proving that Jesus can act like a responsible father will help her get her girl.

It's not hard for a man to act like a responsible father - especially if he can act. But can he be a responsible father? And is it fair to force a baby to be his driver's ed car?

"She's determined not to make the same mistakes [that she did in Malawi] and feels that the only way to do this is to get Jesus involved from the off," a secret source told News of the World.

"Madonna is considering visiting, perhaps with Jesus, as soon as she can. Failure is not an option."

Carradine family seeks answers

David Carradine's family, dissatisfied with Thai investigators and "profoundly disturbed" by the publication of a forensics photo of a bound, nude Carradine in the Bangkok tabloid Thai Rath, have threatened legal action against any media outlet that reprints images of the actor in death.

Half-brother Keith Carradine has also filed reports with the FBI that could lead to the agency's involvement, said celebrity attorney Mark Geragos.

First, the family will seek an independent autopsy by celebrity forensic pathologist Dr. Michael Baden to determine whether another person could have been involved, Geragos said.

Results of an autopsy in Bangkok are not expected back for weeks.

"It's an amazing thing what a good pathologist can accomplish," Geragos said.

A chambermaid found Carradine's body Thursday at Bangkok's Swissotel Nai Lert Park Hotel.

Thai authorities said that they have all but ruled out foul play, said Col. Somprasong Yenthuam, lead investigator.

Investigators initially said that the body was found "naked, hanging in a closet," causing them to suspect suicide.

Police later said that Carradine may have died from accidental suffocation or heart failure after revealing that he was found with a rope tied around his wrist, neck and genitals - leading to speculation that Carradine may have engaged in auto-erotic asphyxiation.

"All we really know is not much more than what the public knows, and that's disturbing," Geragos said.

Carradine flew to Thailand last week and began work on the film "Stre t ch" two days before his death.

Friends and associates told Larry King that he had a happy marriage, a new car and several films lined up after he finished work in Bangkok.

* Security guard Joseph Babnik has been charged with shoving ex-model Stephanie Seymour at her Connecticut home.

Greenwich police tell the Greenwich Time that they arrested Babnik Thursday.

Seymour, 39, and her wealthy, estranged husband, Peter Brant, 62, are divorcing. Police say Babnik watches the estate while Brant is out of the country.

Brant and Seymour have been living in different houses on the estate, which sort of defeats the purpose of marrying a model.
