How Lisa Marie Presley's matching tattoo with her son Ben Keough helped her grieve

When Lisa Marie Presley's son Benjamin Keough died by suicide in 2020 she began living on borrowed time, Elvis Presley's granddaughter Riley Keough told Oprah Winfrey in an exclusive prime-time special "An Oprah Special: The Presleys — Elvis, Lisa Marie and Riley," airing Tuesday on CBS.

"I just couldn't imagine a world where she would make it without him," said Keough as she recalled the final years she shared with her famous mother, and how she processed her brother's death, as she finished co-writing "From Here to the Great Unknown," Lisa Marie's posthumous memoir.

"She would say 'I'm going to die of a broken heart' and I think we felt that," Keough told Winfrey.
