The only child of rock ‘n’ roll legend Elvis Presley, Lisa Marie, has died at the age of 54, her mother has announced.

“It is with a heavy heart that I must share the devastating news that my beautiful daughter Lisa Marie has left us,” Priscilla Presley said.

Lisa Marie Presley, also a singer, was rushed to hospital on January 12. According to media reports, she suffered cardiac arrest.

She was found unresponsive at her home in Calabasas, California, sources told TMZ.

“She was the most passionate, strong and loving woman I have ever known,” Priscilla Presley said in a statement.

“We ask for privacy as we try to deal with this profound loss.”

Her mother gave no details about the possible cause of death.

Citing a source close to Lisa Marie Presley, TMZ reported that the star was found unresponsive in her bedroom. At about the same time her former husband Danny Keough, who also lives at the property, arrived and performed CPR.

The outlet said that the singer had suffered a “full arrest” before a bystander administered epinephrine – commonly known as adrenaline – to help her regain a pulse.

Paramedics arrived shortly afterwards, taking her to hospital.

Born in 1968, Lisa Marie Presley went on to follow in her father’s footsteps and forged a career in music. She released three albums, with her 2003 debut studio album selling hundreds of thousands of copies and receiving generally positive reviews.

Lisa Marie Presley was also well known for a series of high-profile marriages to pop legend Michael Jackson, actor Nicholas Cage and musicians Danny Keough and Michael Lockwood.

She had four children, including the actress Riley Keough. Presley’s son, Benjamin Keough, killed himself in 2020.

Lisa Marie Presley was last seen in public at the Golden Globes Awards in Beverly Hills.

Accompanied by her mother, the pair were seen breaking down in tears as they watched Austin Butler win the Best Actor prize for his portrayal of her father.
