Elvis’ daughter, Lisa Marie, brought up her family in Scientology before a falling out with its controversial leader, David Miscavige, in 2014. Keough committed suicide on Sunday. A friend of his told Ortega — who covers all things Scientology in his blog the Underground Bunker — that back in May, Keough “had been talking about how f - - ked up kids get in Scientology.”

He was raised in the religion with his sister Riley, and their dad, Danny Keough — Presley’s first husband — is still in the church.

Meanwhile, Presley has been going through a bitter divorce from her fourth husband, Michael Lockwood, including a custody battle over their 11-year-old twins, Finley and Harper.

Speaking about Presley, the source told Ortega: “Ben was her baby. More than Riley. More than the twins. This will be beyond inconceivable for her. I really worry that it might be too much for her.”

Another source, who was said to be close to Keough as a boy, claimed, “His entire family was shaped by Scientology, and [they’re] paying the price.”

The 27-year-old shot himself in the chest at his mother’s $1.8 million Calabasas, Calif., mansion. Keough reportedly had a longtime girlfriend, Diana Pinto.

One neighbor reportedly said that Presley was not in the house, and they had not seen her for weeks, according to the Daily Mail. Members of the Presley family gathered there later on Sunday.

Reps for the family and Scientology were unavailable for comment. Presley’s rep previously said in a statement that she was “entirely heartbroken, inconsolable and beyond devastated,” adding, “She adored that boy. He was the love of her life.”
