Elvis Presley's ex-wife Priscilla has stunned fans of the King of rock 'n' roll with her revelation he took vast amounts of sleeping and diet pills.
The actress admits her late husband became dependent on drugs to make him look and feel good as Elvis' career became too much for him to handle.
She says: "He would use amphetamines to stay awake because he would have late-night manoeuvres that would go way into the early morning hours and he was given pills to stay up.
"From there he had to sleep - then get hours of sleep in - so then he would start taking sleeping pills.
"It was just such an accepted thing - diet pills to lose weight before the movie that he had to do... You get used to it because it's easy."
In an exclusive interview on US news show Entertainment Tonight, Priscilla Presley also reveals Elvis tried to help her out by prescribing pills - when she was still a student.
She recalls: "He gave me a pill because I told him I was having a hard time staying awake at school... He was concerned about that and I was visiting him a lot, so he gave me a pill and said: 'Here, I want you to take this.'
"I never took them. I put them in a little box and saved them."
