Wait, Does Madelyn Cline Have A New Boyfriend?

Fresh off the press tour for her most recent movie alongside co-star KJ Apa, Madelyn Cline’s recent NYC getaway has sparked plenty of speculation on the possibility of a brand-new beau. 

The Outer Banks star was spotted around the city in September 2025 with a mystery man, but after a video of the star made the rounds online, an eagle-eyed Deux Moi staffer noted a familiar face by Cline’s side—none other than Prince Constantine-Alexios, eldest son of the crown prince and princess of Greece.  

The pair were spotted kissing just days before the video went viral, and subsequent social media posts have put together quite a picture: Cline, the prince, and his sister, model and tastemaker Maria-Olympia, all out and about at a local bar. Constantine-Alexios‘ Instagram story of Cline facing away from the camera also certainly didn’t help to quell fan rumors. 

Given how fresh the relationship appears to be, details beyond the identity of Cline’s royal beau are limited—sorry helpless romantics, it’s not yet clear how, where, when, or why the pair first met. 

26-year-old Constantine-Alexios comes from a long line of royals—plus, his godfather is Prince William—and boasts a wide array of interests endeavors range from sculpting and painting to modeling for major fashion labels like Dior. The royal has previously dated Poppy Delevingne and Brooks Nader. 

Though just weeks ago, fans thought that Cline may have a budding romance with Zack Bia brewing—the latest instance in a string of speculations occurring between the pair since 2022—neither party has commented on the nature of their relationship. Looking at recent eyewitness proof, though, it seems the Bia ship has sailed—at least where fans are concerned. The I Know What You Did Last Summer actress has previously been romantically linked to Chase Stokes, Pete Davidson, and Jackson Guthy, among others.
