Lisa Marie Presley's son and Elvis Presley's grandson, Benjamin Keough, has died of an apparent suicide ... TMZ has learned.
Law enforcement sources tell us Ben appears to have died Sunday in Calabasas from a self-inflicted gunshot wound.
Not much is known about him other than the fact that he's got a super-famous family. He's the son of Lisa and musician Danny Keough -- and his sister is actress Riley Keough, who's been in a number of indie and horror films over the years, including 2019's "The Lodge."
