Lisa Marie Presley is "beyond devastated" her son Benjamin Keough has died in an apparent suicide.
Benjamin was found dead aged 27 with what police have called a self-inflicted gunshot wound.
His famous mother, 52, is "completely heartbroken" over his death and left "inconsolable" as "he was the love of her life".
The American singer-songwriter is trying to hold it together for her 11-year-old twins Finley and Harper as well as her grown up daughter Riley, 31.
Her tribute to her son is an outpouring of her heartache and grief.
Lisa Marie Presley's representative Roger Widynowsk said on her behalf: “She is completely heartbroken, inconsolable and beyond devastated but trying to stay strong for her 11 year old twins and her oldest daughter Riley.
"She adored that boy. He was the love of her life.”
Benjamin stayed out of the limelight for much of his life.
He was found dead on Sunday in Calabasas.
The musician signed a mega record deal worth $5million when he was just a teenager in 2009.
However, it never seemed to take off and the grandson of Elvis Presley remained fairly unknown.
Lisa had her son Benjamin with her ex-husband Danny Keough.
The exes were married from 1988 until they went their separate ways in 1994.
She has walked down the aisle four times; afterwards she married Michael Jackson, later Nicholas Cage and most recently Michael Lockwood.
Her latest divorce to Lockwood was finalised in 2016.
