Admittedly, Del Rey does bear quite a resemblance to Priscilla. In fact, according to the publication's insider source, "Lana looks just like Priscilla and has decided there's no way she won't get the part."
"Lana feels it's a role she was born to play," they added. "She's has [sic] her agent badgering Baz for months now, hoping to get her cast."
A noted fan of The King, Del Rey previously recorded a song called "Elvis" for a 2018 documentary about Elvis' life. So you can imagine that being cast as Priscilla would be a dream come true.
