This round of speculation will have you feeling déjà vu.

After Olivia Rodrigo released her single "Vampire" at the end of June ahead of the release of her second album Guts, many online immediately took to the task of trying to discover who the breakup ballad could be about. One of the potential sources of inspo? Olivia's ex Zack Bia. However, the DJ doesn't buy into the theory that he's the blood-sucker in question. 

"I don't think it's really about me," Zack told GQ in an interview published Sept. 18 when asked about the song. "I think the Internet just ran with it."

As for the proof? He pointed out that their brief romance wasn't really worthy of such a scathing summary, "Look, I'm in the industry so I know how a song gets made," he added. "We hung out, we're both busy, and we ended up not furthering our relationship. There was never any drama, you know?"

The "drivers license" singer, 20, and Zack, 27, sparked dating rumors back in February 2022, shortly after she and music producer Adam Faze—who the internet suspected as another potential vampire—ended their sixth-month long relationship. 

At the time Olivia and Zack's public appearances got the rumor mill turning, a source told E! News, "He invited her to Super Bowl parties that he was DJing that weekend and she went to support him. They hit it off and have been casually hanging out."

They added, "Zack [feels] that Olivia is really down to earth and he loves how low-key she is. It's a good balance between them."

However, by August, their romance had fizzled out.

Olivia has since been linked to TikToker Vinnie Hacker in the spring of 2022, however the High School Musical: The Musical: The Series alum recently opened up about dating in the public eye.

"I had such a desire to live and experience things and make mistakes and grow after Sour came out, I kind of felt this pressure to be this girl that I thought everyone expected me to be," Olivia told The New York Times in an interview published Aug. 24. "And I think because of that pressure, maybe I did things that maybe I shouldn't have—dated people that I shouldn't have."

And she explained that many of the songs on Guts, which was released on Sept. 8, are "about reckoning with those feelings and coming out of that disillusionment and realizing the core of who I am and what I want to be doing and who I want to be spending my time with."

But despite fans yearning for answers when it comes to the names behind Olivia's songs, after some speculated that "Vampire" could be about Taylor Swift and the drama surrounding the Midnights artist's credits on Sour, Olivia was quick to clarify some things would stay unknown. 

"I never want to say who any of my songs are about," she told The Guardian in an interview published Sept. 2. "I've never done that before in my career and probably won't. I think it's better to not pigeonhole a song to being about this one thing."
