Lisa Marie Presley, the only daughter of legendary rock icon Elvis Presley and actress Priscilla, has died aged 54 from a 'full cardiac arrest' on Thursday.

The mother-of-four was discovered unresponsive by a housekeeper, with sources saying her first husband, Danny Keough, returned to the house they were sharing and performed CPR until paramedics arrived.

EMTs were able to resuscitate her and rush her to a local hospital, but she was pronounced dead a few hours later.

Her mother, Priscilla, was later seen arriving at the hospital to support her daughter - an hour after reports of the medical emergency. 

She eventually released a statement saying: 'It is with a heavy heart that I must share the devastating news that my beautiful daughter Lisa Marie has left us.' 

'She was the most passionate, strong and loving woman I have ever known. We ask for privacy as we try to deal with this profound loss. 

'Thank you for the love and prayers.

At this time there will be no further comment.'

As the only daughter of rock 'n' roll royalty, Lisa Marie was quickly thrust into the limelight as a child and has had her fair share of tragedy.

In recent years, she has opened up about her crippling drug addiction, including painkillers, opioids and cocaine.

While writing the foreword for Harry Nelson's book - The United States of Opioids: A Prescription for Liberating a Nation in Pain - she opened up for the first time about her addiction to painkillers, opioids and cocaine. 

Presley said in the book, written in 2019, that she was 'grateful to be alive today' before explaining that she first started taking opioids after the birth of her twins Vivienne and Finley in 2008.

She said: 'You may read this and wonder how, after losing people close to me, I also fell prey to opioids.

'It only took a short-term prescription of opioids in the hospital for me to feel the need to keep taking them.'

Addiction has been a part of the star's life since she was a child, with her father and ex-husband, Michael Jackson, both dying due to complications from drug use.

Lisa Marie was just nine when she saw her father's dead body slumped face -down on the carpet, as she recalled crying as she said 'my daddy's dead'.

His body was not removed from the property following his death in August 1977, which Lisa Marie previously said made it 'not seem real' to her - adding it was 'oddly comforting'.
