Sarah Ferguson, Duchess of York, stalking JFK Jr

From historian Andrew Lownie's book, which will be released next week and is mostly about Prince Andrew's and Sarah Ferguson's (his ex-wife's) relationship to Epstein and various dictators and arms dealers:

"On A trip to New York, Fergie asked her staff to find out if John Kennedy Jnr – handsome son of the assassinated JFK - was in town and, discovering where he was, she invited him for drinks or dinner at her hotel, which he accepted. On being told that Kennedy had a girlfriend, the actress Daryl Hannah, the duchess replied: 'That's not going to bother me!' But it bothered Hannah, and Kennedy cancelled, claiming a prior engagement. Staff were then ordered to spy on his apartment all night to check that he had told the truth. The duchess was not to be discouraged, especially after learning that Princess Diana had met Kennedy for an hour and a half at Christmas 1995 at a New York hotel. She was furious: 'He's mine! Why can't she just leave him alone?'

She gave Kennedy a code name, 'Number Nine' – his place in the order of her lovers, with Steve Wyatt 'Number One' – and spent hours scouring magazines for articles about him, cutting out pictures of him in his swimming trunks and talking to her friends about whether he would like different aspects of her personality. A close confidante revealed: 'She'll suddenly ask, "Do you think Ken will mind that I don't like such and such a thing?" It's incredibly real to her, like a schoolgirl crush. She spends hours talking about him. The fact that she's never even met him doesn't seem to matter at all.'"

I hadn't realized that JFK Jr met Princess Diana because he wanted her to be in "George" magazine and that RoseMarie Terenzio had written about it: https://people.com/royals/what-really-happened-the-day-jfk-jr-met-princess-diana-and-what-he-said-about-her-after/
