Di-JFK Jr. One-Night Stand?

A book being serialized by Britain's best-selling "Sun" newspaper claims Princess Diana and John F. Kennedy Jr. had a one-night affair in New York, reports CBS News Correspondent Richard Roth on The Early Show.

The account says it was in 1995 at Manhattan's Carlyle Hotel, in a $3,200-a-night suite Diana reportedly described as expensive.

A bachelor at the time, JFK Jr. was said to be urging Diana to agree to an interview for the magazine he published and, Diana is quoted as saying, "One thing led to another."

The book's author is Simone Simmons, described as an 'energy healer' and confidante of Diana.

Says Simmons: "That was the story she told me, that still left me pretty shocked, but … that was Diana. It was just a thing that happened."

Simmons claims Diana later had an astrological chart prepared and concluded she and Kennedy were compatible, but not enough to sustain a relationship.

Simmons' co-author, Majesty Magazine Editor and CBS News consultant Ingrid Seward observes, "Everything else Simone has told me about Diana is absolutely true. And I've been in this business for over 20 years. There's no reason for it not to be (true). She doesn't have to make it up."

Even so, Roth points out, the claim's being dismissed as nonsense by Diana's former butler and by a former bodyguard.

The book in which it appears is called "Diana: The Last Word" which, undoubtedly, it won't be, Roth points out.
