The Death of Diana: New Questions| Princess Diana

Was Diana Pregnant?

Rumors that Diana was carrying Dodi's child surfaced soon after her death – and were quickly denied by her friends. But Dodi's father has charged that Diana's embalming within hours was done to hinder a thorough post-mortem exam. Investigators have taken this concern seriously enough that earlier this year they reinterviewed doctors at Paris's Pitié-Salpêtrière hospital, where Diana was taken after the crash.

Adding to the mystery, Diana looked to some as if she had the beginnings of a pregnancy tummy when she was photographed with Dodi just days before her death. From his yacht, on Aug. 28 and 29, five calls were made to Dodi's friends at a villa in Europe, including a call in which he "intimated the couple had wonderful news to share," an investigator says. Al Fayed claims to have "indisputable" proof that Diana was about nine weeks pregnant when she died. A member of Al Fayed's staff would say only "we are making our submissions to the appropriate authorities."

But, PEOPLE has learned, investigators have ruled out the pregnancy theory. "It is completely fictitious – without any foundation at all," one says. Bolstering their view: statements from two doctors from the French hospital who "knew exactly what state Diana was in, and she definitely was not pregnant," an investigator says.
