Furthermore, she continued to have access to the jewellery that she had received during her marriage, and was allowed to use the air transport of the British royal family and government. Diana was also offered security by Metropolitan Police's Royalty Protection Group, which she benefitted from while travelling with her sons, but had refused it in the final years of her life, in an attempt to distance herself from the royal family. Diana retained close friendships with several celebrities, including Elton John, Freddie Mercury, Liza Minnelli, George Michael, Michael Jackson, and Gianni Versace, whose funeral she attended in 1997. She dated the British-Pakistani heart surgeon Hasnat Khan, who was called "the love of her life" by many of her closest friends after her death, and she is said to have described him as "Mr. Wonderful".

After deciding against a trip to Thailand, she accepted Fayed's invitation to join his family in the south of France, where his compound and large security detail would not cause concern to the Royal Protection squad. Mohamed Al-Fayed bought the Jonikal, a 60-metre multimillion-pound yacht on which to entertain Diana and her sons. Tina Brown later claimed that Diana's romance with
