Who Are Olivia Rodrigo's 'Guts' Songs About? Here Are All the Fan Theories

‘Vampire’ – Zack Bia

In “Vampire,” Olivia sings about a “bloodsucker, fame f-cker, bleeding me dry like a goddamn vampire.” Using vampire-related imagery, she describes a situation where she was taken advantage of in a relationship. Many fans related the narrative to Zack Bia, a DJ and party promoter who Olivia reportedly dated for six months in 2022. (She references “parties” and “diamonds” in the tune.)

In the second verse, she croons, “And every girl I ever talked to told me you were bad, bad news / You called them crazy, God, I hate the way I called them crazy too.” Zack doesn’t exactly have a great reputation when it comes to dating famous women…there’s a viral video of him making the singer, Madison Beer, cry.

Madison‘s heartbreaking song “Selfish,” widely believed to be about Zack, had a surge in streaming after Olivia released “Vampire.” In response to that news, Madison wrote, “Thank u miss olivia <3," in a since-deleted tweet.

Another clue about “Vampire” is in the lines, “Went for me and not her / ‘Cause girls your age know better.” Zack is notably seven years older than Olivia.
