Benjamin Keough, Elvis Presley’s only grandson, died on Sunday at the age of 27.
The news was confirmed by his mother Lisa Marie Presley’s manager.
Manager Roger Widynowski gave no further details about his death, BBC reports.
He said Lisa Marie, 52, was “heartbroken, inconsolable and beyond devastated”.
He was the younger of the two children Lisa Marie Presley had with her first husband, musician Danny Keough, before their divorce in 1994. The other is actress Riley Keough, 31.
Lisa Marie had previously described Keough’s resemblance to her famous father as “just uncanny.” Rock ‘n’ roll legend Elvis Presley died in 1977 aged 42.
