Priscilla Presley fears people will forget about her ex-husband Elvis

She shared: "My fear is that people will forget about Elvis. I feel a responsibility for keeping his legacy alive. You'll never see his sort of stardom again.

"He was so authentic and, in lots of ways, innocent. What you saw was what you got."

Priscilla first met the 'Heartbreak Hotel' hitmaker during her teens and she admitted it was a life-defining moment for her, even though their marriage did not work out.

She explained: "Meeting Elvis when I was 14 changed the course of my life. Sure, that was young, but he left Germany [where they had met] to return to the US not long after.

"We stayed in touch for two years before we saw each other again. He was a gentleman in all ways while we courted."

The Grammy Award-winning star died in 1977 in Memphis, Tennessee, at the age of 42. And Priscilla admits he would have struggled to cope with his level of fame were he alive in the 21st century.

She told the Guardian newspaper: "Elvis would have found modern times difficult. He was an intensely private man who was quite protected by his inner circle.

"The way he lived then wouldn't be possible in 2016. Our lives - whether you're famous or not - are so public now."
