EXCLUSIVE: New Princess Diana Special Delves Into Her 'Passionate' Love Life and Her Greatest Fear

By
Get ready to see the late Princess Diana in a whole new light.
ET has the exclusive trailer for ABC News' upcoming Princess Diana special, The Last 100 Days of Diana, which focuses on the beloved royal's personal life and in particular the summer of 1997. Diana died in a car crash in August of that year.
The special features interviews with a few of Diana's closest friends, including designers Lana Marks and Roberto Devorik.
"It was beyond royalty, it was beyond Hollywood -- this was it," Marks says of Diana's glamorous life.
Diana's relationships with Dr. Hasnat Khan -- who is described as "the love of her life" -- and the late Dodi Fayed, are also discussed in the film, particularly, Fayed and Diana's "sexual attraction" towards one another.
"Suddenly, after all this time, she found passion," one commentator notes.
Of course, Diana's love for her two sons, Prince William and Prince Harry, is also covered in the special.
"Diana often did say that her boys were not really hers because they belonged to the royal family," one commentator recalls.
"The one thing she feared in life was losing her children," another close friend confirms.
The Last 100 Days of Diana airs Sunday, May 7, at 9 p.m. EST on ABC.
Earlier this month, Prince Harry opened up about losing his mother at age 12, and how it had a serious effect on him.
"My way of dealing with it was sticking my head in the sand, refusing to ever think about my mum because why would that help?" he told the Telegraph's Bryony Gordon in the first episode of her new podcast, Mad World. "I've spent most of my life saying 'I'm fine' … and most of us aren't up for going that deep."
