Lisa Marie Presley hospitalised after heart attack, US media says

Lisa Marie Presley, the only child of Rock legend Elvis, has been rushed to hospital after suffering a suspected cardiac arrest, US Media has reported.

The singer, 54, was found unresponsive at her home in Calabasas, California, sources told US outlet TMZ.

The LA County Fire Department told CNN that emergency responders had been dispatched to an address in the city.

But they declined to confirm the name of the patient, who they said was rushed to hospital.

Sources close to the star told TMZ that Presley had suffered a "full arrest" before a bystander administered epinephrine - commonly known as adrenaline - to help her regain a pulse. Her current condition is unclear.

Presley's agent refused to comment on the reports, but US media said her mother Priscilla was seen arriving at the West Hills hospital in Los Angeles.

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

The star is 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 three children, including the actress Roxy Keough.

Presley was last seen in public on Tuesday night at the Golden Globes Awards in Beverley 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.

During an emotional speech, the actor thanked the Presley family for their help during the film.

"Thank you guys, thank you for opening your hearts, your memories, your home to me," Butler said. "Lisa Marie, Priscilla, I love you forever."
