Lisa Marie would wed a third time, to actor Nicolas Cage, in 2002 when Benjamin was 9 years old. That marriage lasted 108 days before Cage filed for divorce.
Presley's longest-lasting marriage was her fourth, to guitarist Michael Lockwood, who she divorced after a decade in 2016. That union gave Benjamin two younger sisters: twins Harper and Finley, born in 2008.
Benjamin shared a striking resemblance to his late grandfather, something his mother herself once acknowledged in an interview, revealing he'd caused quite a stir when he accompanied her to a performance at the iconic Grand Ole Opry in 2012.
"Ben does look so much like Elvis. He was at the Opry and was the quiet storm behind the stage. Everybody turned around and looked when he was over there. Everybody was grabbing him for a photo because it is just uncanny," she said.
The vast Presley fortune has dramatically dwindled in recent years, with Benjamin's mother Lisa Marie claiming her former business manager squandered her entire share of Elvis' $152 million (US$100 million) fortune.
In 2018 court documents, Lisa Marie alleged that Barry Siegel assured her that her finances were in "good shape" while he whittled her $152 million (US$100 million) trust down to just $21,000 (US$14,000) in poor investments.
Last year Benjamin's grandmother Priscilla Presley was forced to sell her Los Angeles mansion to help her daughter out with her mounting debts.
"Priscilla would never have done this if she didn't believe it was her daughter's last chance," a source told Radar of the $8.3 million (US$5.5 million) sale at the time.
The most recent photo of Benjamin on his mother's Instagram account was posted in June of last year. It shows Lisa Marie with her two older children, Benjamin and Riley, alongside her younger twin daughters from her fourth marriage to guitarist Michael Lockwood.
"Mama lion with cubs," she captioned the sweet family pic.
And in a statement provided to EW today, a representative for Lisa Marie said she was "beyond devastated" over her only son's death.
"She is completely heartbroken, inconsolable and beyond devastated but trying to stay strong for her 11-year-old twins and her oldest daughter Riley," the statement read. "She adored that boy. He was the love of her life."
