Diana's 'True Love' Speaks for the First Time

When the people's princess died, it was ex-flame Hasnat Khan, a Pakistani surgeon, whom Diana truly still loved and not Dodi Fayed, who was just a rebound, Diana's former personal butler Paul Burrell testified Monday.

"This was the man she loved more than any other," Burrell told the court. Her relationship with Fayed was an attempt to make Khan jealous and a rebound from their breakup, he said.

The Pakistani heart surgeon, who supposedly carried on a two-year relationship with Princess Diana, said he hopes her former butler's testimony will put to rest any questions people had about his relationship with the princess.

"I hope it settles all the questions, which have been asked, and for me, I think it's important that this is the end of it," Khan said, when he broke his 10-year silence on the subject.

Khan, who attended Diana's funeral, broke up with her just two months before she died. She touted him as "Mr. Wonderful."

"Diana loved him and I think he loved her, but he wasn't prepared to give up his hard-earned career," said royal author Robert Jobson.

Best-selling author Tina Brown said Khan broke his decade-long silence because he was tortured by the subject.

"He was unable to have any piece of mind from any piece of the week," Brown said on "Good Morning America" today. "I think he just felt the pressure now to clear his position to move on."

Khan wasn't prepared for life in the public eye on the arm of the most photographed woman in the world.

"He knew [their relationship] was only possible because it was secret and Diana valued him so much she was able to keep it secret," Brown said. "Diana was very good at keeping secrets."

During Burrell's testimony, he said Diana asked him to explore the possibilities of a secret wedding to Khan and added the princess' mother called her a whore for messing around with Muslim men.

"She really believed she could marry Khan," Brown said. "She did continue to have that fantasy."

This was in spite of the fact Khan knew he could never marry Diana and found the idea of a secret wedding impossible and absurd, Brown added.

Still, he loved her deeply and would testify during the inquest if the law required him to do so because he has nothing to hide, Brown said.

The relationship between the two became quite domestic, with the princess sneaking down to microwave his dinner in the palace after the staff had left for the day, Brown added. Khan also spent time with her sons and Diana enjoyed his gentleman ways.

In fact, he wouldn't consummate their relationship until her divorce was official, Brown said.

More information about Diana and her life is poised to come out today when Burrell takes the stand again. He said he has a lot more information and was asked to produce more evidence to back his claims. But some of Diana's secrets, Burrell said, "will go with me to the grave."

He added that accusations about Prince Charles having a hand in Diana's death were unlikely.

"I don't believe Charles was capable of murdering the princess," Burrell said referring to the one of the princess' purported handwritten notes in which she claimed Charles was "planning an accident in my car, brake failure and serious head injury."
