Smith Balks at DNA Test

Anna Nicole Smith has no intention of allowing her 6-week-old daughter to undergo a paternity test, according to her attorney. Smith's ex-boyfriend, photographer Larry Birkhead, is seeking a court order to force Smith to bring the girl from the Bahamas to California for a DNA test. A birth certificate lists Smith's current boyfriend, Howard K. Stern , as the father of Dannielynn Hope Marshall Stern .

An attorney for Birkhead, Debra Opri , has said she is traveling to the islands this weekend to take depositions from Smith and Stern on Monday.

Smith buried her 20-year-old son, Daniel , on Thursday. He died while visiting his mother in a Nassau hospital three days after the baby was born on Sept. 7.

A pathologist hired by Smith said Daniel died of an accidental combination of methadone and two antidepressants. The results of official toxicology tests and a police investigation have not been publicly released.
