London, Feb 7 : Princess Diana's lover Dodi Al Fayed had all-night sex sessions with an underwear model, while wooing the princess in the day, the inquest into their deaths has heard.
Dodi's former girlfriend Kelly Fisher said that he "seduced Diana all day and f*****me all night".
Fisher, an American underwear model, has already appeared as a witness at the hearings claiming that she and Dodi were engaged when he began a relationship with the Princess in 1997 only weeks before they were killed in a car crash in Paris.
A transcript of the conversation, in which Fisher furiously accused Dodi of two-timing her with the Princess, was read aloud to the inquest jury at the Royal Courts of Justice in London.
The model said that Dodi flew her to the south of France in his private jet in the summer of 1997.
But he had also flown Diana to St Tropez for a holiday on his father Mohamed al Fayed's yacht.
When Fisher saw newspaper pictures of Dodi and Diana together on the yacht, she phoned to confront him.
In the call, Fisher claims that Dodi even spoke to her of marriage during one of his holidays with Diana. At one point she says: "You told me you didn't even like her... why do you suddenly like her?"
She branded Dodi a "liar" during that conversation and he called her "crazy" and "hysterical," reports Times Online.
He also refused to discuss the question of engagement on the telephone.
Having heard second-hand through the press that Dodi was seeing Diana, a livid Fisher phoned Mohamed al Fayed in the middle of the morning only to have him "threaten" and call her a string of names, the jury heard.
Fisher, who lives in Los Angeles, also confronts Dodi over the now-famous pictures of the couple together holidaying on Al Fayed's yacht that August.
As Dodi insists he and Fisher had already broken up, she hits back: "You are f****** crazy. We were together the whole time and you knew it. You knew it."
