Hollywood is weird. One minute you're the face of a Netflix juggernaut, and the next, you're spotted at a Lakers game with a guy who seems to know every single person in the room. That’s basically the vibe whenever Madelyn Cline and Zack Bia end up in the same zip code. If you’ve spent any time on TikTok or scrolled through DeuxMoi lately, you know their names have been linked more times than a chain-link fence. But are they actually a couple, or is this just another case of "two famous people had dinner once so they must be getting married"?
The truth is a bit more tangled. It's not a straightforward "met, dated, broke up" story. Instead, the Madelyn Cline Zack Bia saga is a years-long series of "are they or aren't they" moments that have kept fans guessing from Los Angeles to London.
The First Spark: Santa Monica and Birthday Courtside Seats
Let’s rewind to late 2021. Madelyn had just come off a very public, very high-profile breakup with her Outer Banks co-star, Chase Stokes. The "Obx" fandom was in shambles. Then, seemingly out of nowhere, she’s seen grabbing dinner at Giorgio Baldi in Santa Monica—the ultimate celeb-spotting lair—with Zack Bia.
Now, if you don't know who Zack Bia is, he's sort of the Kevin Bacon of the Gen Z social scene. He’s a DJ, a record label founder, and a guy who somehow has Drake’s personal cell number. He’s also known for dating some of the most famous women in the world, including Madison Beer and Olivia Rodrigo.
A few days after that dinner, they were seen together again. This time it was at a Lakers game for Madelyn’s 24th birthday. Naturally, the internet lost its mind. You don't just go to a Lakers game with a "friend" on your birthday, right? Well, according to Zack, you actually do.
What Zack actually said about the rumors
When the noise got too loud, Zack hopped on the BFFs podcast with Dave Portnoy and Josh Richards. He didn’t dodge the question, but he didn't give the answer shippers wanted either. He basically said they weren't dating. His exact vibe was: "We hang out all the time, we enjoy each other's company, but there’s no official title."

He famously remarked that they probably would never "officially stop" dating because they never "officially started." It’s that classic LA "situationship" talk that makes everyone’s head spin. He emphasized that their schedules were just too crazy for anything serious.
The 2025 London Rekindling: Back on the Radar
For a while, things went quiet. Madelyn moved on to a relationship with Jackson Guthy and then had a much-discussed stint with Pete Davidson. Zack was busy being... well, Zack Bia. But fast forward to June 2025, and the Madelyn Cline Zack Bia rumors came roaring back to life across the pond.
The duo was spotted at the Audemars Piguet 150th Anniversary Celebration in London. And honestly? This didn't look like "just hanging out."
- The Sighting: A TikTok video went viral showing Zack standing behind Madelyn.
- The Interaction: He was seen rubbing her arms and whispering in her ear.
- The Vibe: It was intimate. Very intimate.
When a guy is rubbing your shoulders and whispering in your ear at a high-end watch party in London, the "we're just friends" excuse starts to feel a little thin. Media outlets like E! News and People immediately reached out for comment, but as usual, the reps stayed silent.
Why Do People Care So Much?
It’s the contrast, mostly. Madelyn is the "all-American girl next door" (who can also survive a treasure hunt in the marsh), and Zack is the quintessential nightlife king. People love to analyze Zack’s "pull." There's a whole corner of the internet dedicated to figuring out how he consistently dates the most sought-after women in Hollywood.

But there's also the Outer Banks factor. Fans are fiercely protective of Madelyn. After the emotional rollercoaster of her split from Chase Stokes, they want to see her happy. Whether that’s with a DJ or, more recently, rumors of her being linked to Prince Constantine-Alexios of Greece, the interest never wanes.
The Prince Alexios Complication
To make things even more confusing for those following the Madelyn Cline Zack Bia timeline, late 2025 brought a new player into the mix. Madelyn was spotted in New York City looking very cozy—and even kissing—Prince Constantine-Alexios of Greece and Denmark.
Wait, what?
Yeah, the plot thickened. While the London sighting with Zack in June 2025 was steamy, by September 2025, the evidence was pointing toward a royal romance. This is the reality of modern celebrity dating: sightings can be months apart, and the "truth" changes with every new set of paparazzi photos.
The "Situationship" Reality
Honestly, the most likely scenario is that Madelyn and Zack have one of those enduring, low-pressure friendships that occasionally flirts with something more. In her Nylon interview back in 2024, Madelyn mentioned that she realized parts of her life are only for her or one other person to know. She’s become a pro at guarding her privacy.

She’s even joked about the public’s obsession with her dating life, saying "the jokes write themselves." She knows that every time she’s seen with a guy, it’s going to be a headline.
What’s the Current Status in 2026?
As of January 2026, there is no official confirmation that Madelyn and Zack are a "couple." While the London embrace was the peak of the recent rumors, the subsequent sightings of Madelyn with Prince Alexios suggest that if she and Zack were ever "on," it might have been a brief rekindling or simply a very affectionate friendship.
Zack continues to be the guy everyone knows, and Madelyn continues to be the star everyone wants to know more about.
What you should take away from this:
- Casual is the keyword: If Zack's past interviews are any indication, he avoids labels like the plague.
- Privacy is priority: Madelyn has explicitly stated she wants to keep her intimate life out of the "frenzy."
- The "Bia Effect" is real: Whether they are dating or not, Zack Bia remains one of the most well-connected figures in the young Hollywood social scene.
If you’re trying to keep up with Madelyn’s heart, don’t look for an Instagram-official post anytime soon. She’s moved past the era of public declarations. Instead, keep an eye on the background of party photos and the blurry TikToks from exclusive events. That’s where the real story usually hides.
Next time you see a headline about them, remember the London whispering—it was real, but in Hollywood, "real" doesn't always mean "forever." It just means they were having a really good night in London.
To get the most accurate picture of what's happening now, look for recent sightings in NYC or LA over the last month, as Madelyn’s circle has shifted significantly toward the East Coast social scene lately. Following the social media tags of their mutual friends, like the Outer Banks cast or the "No Vacancy Inn" crew, often provides more context than a standard tabloid report.
