Olivia Rodrigo once (allegedly) described Zack Bia as a “bloodsucker, fame-fucker” who bled her dry “like a goddamn vampire.” Yes, her smash hit, “Vampire,” is rumored to be about her brief fling with the toxic DJ version of Pete Davidson. And she’s not the only iconic pop star who’s written a song about this dude (*cough* Madison Beer)! Based on his face and his aura, I’d say Zack falls squarely into the “rat” category of straight men. Yet somehow, he’s most famous for being linked to several beautiful, famous pop stars and actresses. No one knows shit about his mysterious DJ-ing career, that’s for sure.

Most recently, this man was spotted cozying up to none other than goddess Madelyn Cline at Audemars Piguet’s 150th anniversary celebration in London, which begs the urgent question: How the fuck is he pulling all of these incredible celeb women when he’s A.) not remotely in their league and B.) clearly not treating any of them well? Here’s everything to know about Zack Bia’s baffling dating history.

Zack’s most famous relationship was with Madison Beer — they dated on and off from 2018 to 2019, and there’s a very upsetting video of him making her cry. Shortly after their split, Madison tweeted: “Before you diagnose yourself with depression and anxiety make sure you’re not just surrounded by assholes and people who don’t care about you.” She also (almost definitely) wrote about their breakup in her 2020 hit, “Selfish,” which happens to be one of my favorite songs ever. “I bet you thought you gave me real love / But we spent it all in nightclubs,” she croons. “All you ever wanna do is lie / Why you always such a Gemini?” Yes, Zack is a Gemini who certainly spends lots of time in nightclubs.

After Madison, Zack was linked to Olivia Rodrigo in early 2022. He attended her 19th birthday party when he was… 25. Not weird at all! They were spotted spending time together in New York City on multiple occasions. In a 2023 interview with The New York Times, Olivia said, “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 … Maybe I did things that maybe I shouldn’t have — dated people that I shouldn’t have.”

In “Vampire,” Olivia sings about an age-gap relationship: “You went for me and not her / Because girls your age know better.” Madison responded to a Pop Crave post revealing that “Selfish” had seen an increase in downloads after Olivia released “Vampire.” She joked, “Thank [you] miss olivia <3,” but later deleted the tweet.

Are Zack Bia And Madelyn Cline Dating?

I fear these two seem to have rekindled an old flame… They dated back in 2021 and 2022, and this recent sighting definitely seems couple-y. At Audemars Piguet’s 150th anniversary celebration in June, Zack was spotted resting his hands on her shoulders and bringing them down her arms. He also leaned down and put his hands around her waist, whispering in her ear. You can watch the TikTok and judge for yourself, but doesn’t seem platonic to me! My professional advice for Madelyn (based on “Selfish” and “Vampire”) is: Run.
