Burrell explains: "Diana declined an offer to move into the professional sphere of her future daughter-in-law, Meghan, and become an actress. "She was approached to appear in The Bodyguard II alongside Kevin Costner. I'm not sure but yes, OK, send it and I promise I will have a look.' "She told me at the end of the call that he had offered her the lead role in a follow-up to the smash hit which had starred Whitney Houston as the lead. "She was to play a princess and Kevin would be her bodyguard and save her life.
