    A plethora of royal love stories have made it to the big screen, from The Prince and Me to Red, White, and Royal Blue. Now, a real-life prince has found himself at the center of a regal Hollywood romance, after being photographed kissing a famous actress.

    Prince Constantine-Alexios is the dashing royal protagonist in this story, and the alleged object of his affection is none other than Outer Banks star Madelyn Cline. According to Hello! magazine, Cline has been hanging out with Contantine-Alexios in New York, where his parents—Crown Prince Pavlos and Crown Princess Marie-Chantal—have a home.

    Per the outlet, Constantine-Alexios and the I Know What You Did Last Summer star were photographed kissing, with the snap gaining traction on social media. "The pair were previously spotted dining together in Manhattan, while a video showed them holding hands as they walked down a street," the publication noted.

    Constantine-Alexios grew up in London, before relocating to the United States to attend Georgetown University; he graduated in 2022, Us Weekly reported. Since then, the royal has worked as a model for Dior, and as a painter and sculptor. He is also Prince William's godson, giving him an important connection to the British Royal Family.

    Pavlos, Crown Prince of Greece, Marie-Chantal, Crown Princess of Greece, and their sons, Prince Constantine Alexios and Prince Aristides Stavros, arrive at the Royal Wedding of Prince Nikolaos of Greece with Chrysi Vardinoyannis in St. Nicholas Ragavas, in Athens, Greece, on February 7, 2025

    During an interview with Remix Magazine in March 2023, Cline dished on how she knows she's in love with someone. "The initial signs are obviously that giddiness and the butterflies," the actress explained. "But even after that, there's even deeper feelings where I feel completely at ease and comfortable and so full of love."
