Benjamin Keough, son of Lisa Marie Presley and singer-songwriter Danny Keough and grandson of Elvis and Priscilla Presley, has died at the age of 27. He reportedly died by suicide in Calabasas, California, on Sunday.

Presley's representative Roger Widynowski said in a statement Sunday that she was `heartbroken` after learning about the death of her son. He is the grandson of the late Elvis Presley.

`She is completely heartbroken, inconsolable and beyond devastated but trying to stay strong for her 11-year-old twins and her oldest daughter Riley,` Widynowski says. `She adored that boy. He was the love of her life.`

`He was at the Opry and was the quiet storm behind the stage!` she told CMT. `Everybody turned around and looked when he was over there. Everybody was grabbing him for a photo because it is just uncanny. Sometimes I am overwhelmed when I look at him.`
