Madelyn Cline is currently the internet’s favorite riddle. One day she’s the queen of the Pogue gallery, and the next, she’s literally being spotted with royalty. If you’ve been scrolling through TikTok or checking DeuxMoi lately, you know the question is Madelyn Cline dating hasn't just been a curiosity—it’s been a full-blown investigation.
Honestly, it’s hard to keep up. After her very public era with Outer Banks co-star Chase Stokes, Madelyn seemed to pivot. She went from the "it-couple" of Netflix to a more guarded, almost mysterious approach to her love life. But in the world of paparazzi and eagle-eyed fans, "guarded" doesn't mean "invisible."
Right now, the buzz isn't about a co-star. It’s about a Prince.
The Royal Rumor: Madelyn and Prince Constantine-Alexios
In late 2025, the internet basically broke when photos surfaced of Madelyn and Prince Constantine-Alexios of Greece and Denmark. We’re talking full-on PDA. They were spotted at The Lions Bar in New York City, and it wasn't just a "friendly dinner." Sources saw them kissing and looking incredibly cozy.
Soon after, a video made the rounds of the two walking hand-in-hand through the streets of Manhattan. It felt like something out of a movie—the South Carolina girl and the Greek royal.
As of January 2026, neither has posted a "hard launch" on Instagram. Madelyn is notoriously private these days. She told Cosmopolitan back in 2023 that she realized the "repercussions of inviting so many people into something intimate." She’s clearly sticking to that. While they haven't put a label on it for the public, the evidence from the New York sightings suggests they are very much a thing.
That Pete Davidson Chapter (And Why It Ended)
Before the Prince entered the picture, there was the Pete Davidson era. It was short, chaotic, and exactly what you’d expect from a Pete Davidson relationship.

They started dating around September 2023. It began with a low-key breakfast at the Beverly Hills Hotel and quickly escalated to Madelyn attending his stand-up shows in Vegas. For about ten months, they were the "unexpected duo."
They broke up in July 2024.
Why? It sounds like the classic "schedules and priorities" excuse, but Madelyn actually gave a pretty funny quote to Nylon about it later. She said, "The jokes write themselves," referencing Pete’s famous dating history. She also mentioned he has a "really cute dog" and "great girlfriends now," suggesting there’s no bad blood. It was just one of those 20-something flings that burned bright and fizzled out.
The Ghost of Zack Bia
Interestingly, Zack Bia’s name keeps popping up. They were first linked way back in 2021, right after she and Chase Stokes split. Zack went on a podcast at the time and insisted they were just friends who "hang out all the time."
But then, in June 2025, they were spotted together again in London at an Audemars Piguet event. There was some rubbing of shoulders and whispering in ears.
Is she dating him? Probably not. Zack Bia is the ultimate social butterfly of the LA/London scene. Most insiders think they’re just part of the same elite circle. When the Prince rumors started a few months later, the Zack Bia talk pretty much evaporated.

The Breakup That Started It All: Chase Stokes
We can’t talk about who is Madelyn Cline dating without looking back at Chase Stokes. That was the "identity-defining" relationship for her.
They dated from June 2020 to October 2021. It was the height of Outer Banks mania. Fans weren't just watching Sarah Cameron and John B; they were watching Madelyn and Chase.
When they split, it wasn't just a breakup; it was a PR nightmare. They had to keep filming the show together as a couple while their real-life relationship was in tatters. Madelyn recently admitted on the Therapuss podcast that she "didn't know which way was up" after that split. It’s the reason she’s so hush-hush now. She doesn't want her identity tied to a man again.
What Most People Get Wrong About Her Status
A lot of people think Madelyn is "dating around" because she’s frequently spotted with different men. But if you look at the timeline, she’s actually a serial long-term dater.
- Chase Stokes: ~1.5 years
- Jackson Guthy: ~1 year
- Pete Davidson: ~10 months
She isn't just doing "week-long flings." When she’s with someone, she’s usually with them—living together, sharing dogs, the whole nine yards.
The current situation with Prince Constantine-Alexios seems to be her most serious venture since Pete. It’s also the most high-stakes, considering his family background and her rising status in Hollywood.

Why Her Privacy Matters in 2026
Madelyn is entering a new phase of her career. With Outer Banks moving into its final chapters and her success in Glass Onion, she’s trying to be seen as an Actor, not just a Celebrity.
By keeping her relationship with "Tino" (as friends call the Prince) off her main feed, she’s controlling the narrative. You won't see a "Get Ready With Me for a Date" video from her. She’s learned that once you give the internet an inch, they take a mile.
So, Is She Taken?
Yes. All signs point to Madelyn Cline being off the market and currently seeing Prince Constantine-Alexios.
While they are playing it cool, the multiple sightings in New York and the "proud of you" comments from co-stars like KJ Apa on related news posts are pretty much the confirmation we need. She’s happy, she’s working, and she’s seemingly found someone who operates on the same level of fame—or higher.
If you’re looking to follow her journey, keep an eye on New York street style accounts rather than her Instagram. That’s where the real updates are happening.
Actionable Insights for Fans:
- Don't expect a hard launch: Madelyn has explicitly stated she regrets how public her past relationships were. She likely won't post her boyfriend on her grid unless it’s an engagement or a very long-term milestone.
- Check the background: Many "sightings" are just her hanging out with her tight-knit Outer Banks family. Don't mistake a dinner with Drew Starkey or Austin North for a new romance.
- Watch the press tours: Madelyn usually drops small hints about her happiness during magazine interviews (Vogue, Allure, Cosmo) rather than on social media.
