Lisa Marie Presley, the singer-songwriter and only child of Elvis Presley, died on Thursday at the age of 54 after being hospitalised earlier that day, her mother said in a statement.
"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 in a statement.
"She was the most passionate, strong and loving woman I have ever known."
The announcement came just hours after Priscilla Presley confirmed her daughter had been rushed to hospital.
Los Angeles County paramedics were dispatched to a Calabasas home at 10.37am local time, following a report of a woman in full cardiac arrest, according to Craig Little, a spokesperson for the county's fire department. Property records indicated Presley was a resident at that address.
Paramedics arrived about six minutes later, Mr Little said. A subsequent statement from the Los Angeles County Sheriff's Department said paramedics performed CPR and "determined the patient had signs of life" before taking her to a hospital in nearby West Hills immediately.
The city of Calabasas is nestled between the foothills of the Santa Monica and the Santa Susanna Mountains, about 30 miles northwest of downtown Los Angeles.
Presley was born in 1968 and was the owner of her father's Graceland mansion in Memphis, a popular tourist attraction. She was nine-years-old when Elvis died at Graceland in 1977.
