In 2020, Lisa Marie Presley's son Benjamin Keough died by suicide at the age of 27. Last July, she marked the second anniversary of Keough's death on Instagram, sharing a photo of their matching foot tattoos.

Lisa Marie Presley, was previously married to Michael Lockwood, Nicolas Cage, Michael Jackson, and Danny Keough. In addition to her late son, she was the mother of actress Riley Keough, Finley Aaron Love Lockwood, and Harper Vivienne Ann Lockwood.

In September, Lisa Marie Presley wrote an essay for National Grief Awareness Day, in which she opened up about the loss of her son.

"My and my three daughters' lives as we knew it were completely detonated and destroyed by his death. We live in this every. Single. Day," she wrote. "Grief is something you will have to carry with you for the rest of your life, in spite of what certain people or our culture wants us to believe. You do not 'get over it,' you do not 'move on,' period."

Lisa Marie Presley also said in the essay that she found comfort in the company of people who have faced similar tragedy, adding that her daughters help keep her going.

"I keep going for my girls," she wrote. "I keep going because my son made it very clear in his final moments that taking care of his little sisters and looking out for them were on the forefront of his concerns and his mind. He absolutely adored them and they him."
