More than 40 years after his death, Elvis Presley's fans are still mourning the King of Rock and Roll.
Now his ex-wife, Priscilla Presley, is paying tribute to her late husband.
She's also shining a light on the "final chapter" of his life, and the drug addiction that killed him at a tragically young age.
"He knew what he was doing."
Priscilla is promoting a new HBO documentary about her ex-husband's life, The Searcher, which she also produced.
The movie chronicles Elvis's life from birth to his final recording session in 1976.
At an event for the movie at the SXSW festival, Presley was candid about losing the musician to his prescription painkiller addiction.
“It was difficult for all of us, we certainly didn’t see it coming. But we certainly saw the journey he was taking," she revealed.
“People go, well, ‘Why didn’t anyone do anything?’ Well, that’s not true. People there in the inner group did, but you did not tell Elvis Presley what to do.
You did not. I mean, you’d be out of there faster than a scratched cat. They would try and no way. He knew what he was doing.”
In The Army
Presley also revealed that Elvis started experimenting with drugs during his time in the Army.
While stationed in Germany - where he first met Priscilla - Elvis was given pills to stay awake during guard duty.
"And if you take a sleeping pill, you have to do something to get yourself awake," Priscilla explained.
"He was in unchartered territory, he truly was, and he did this and tried to do this alone.”
But when his addiction finally took its toll on Elvis, Priscilla says she was as shocked as anyone else.
