The 20-year-old son of Anna Nicole Smith died suddenly in the Bahamas on Sunday; three days after the former Playboy Playmate gave birth to a girl.

"We have yet to learn the cause of death but do not believe that drugs or alcohol were a factor," Stern said in the statement. "Anna Nicole is absolutely devastated by the loss of her son. He was her pride and joy and an amazing human being."

Daniel Smith was in the Caribbean nation where his mother, 38, gave birth to a healthy girl on Thursday, Stern said.

He appeared in "The Anna Nicole Show," a reality TV series that aired on the E! Cable channel.

Smith has not said who fathered her second child.
