At 26, Constantine Alexios, the eldest son of Greek Crown Prince Pavlos and Marie-Chantal Miller, has firmly established himself as one of the most talked-about bachelors among European aristocracy. However, public attention is drawn not to his dynastic prospects but to his vibrant personal life. To family and friends he’s simply Tino, but to tabloids, he is a modern playboy whose heart, it seems, can only be captured by the brightest stars. His list of romantic interests reads like a Hollywood blockbuster cast, featuring exclusively famous models and actresses. This approach to choosing companions is reminiscent of the escapades of his older “colleagues” in royal circles, such as Danish Crown Prince Frederik or Prince Albert of Monaco in their youth.
The latest chapter in the young heir’s romantic chronicles seems to be unfolding right now on the streets of New York. Rumors about his romance with 27-year-old American actress Madelyn Cline are gaining momentum. The couple was spotted in one of the city’s bars embracing, and photos of them kissing and holding hands while strolling through Manhattan leave little room for speculation. Although there have been no official statements, the prince himself fueled the fire by posting a mysterious photo on his social media, which is believed to show the back of the Netflix ‘Outer Banks’ star.
Madelyn Renee Cline herself is equally prominent in the entertainment world. The North Carolina native rose to fame for her role as Sarah Cameron. Her career also includes appearances in headline projects like the sequel to the detective saga “Knives Out” and various horror franchises. Cline is no stranger to relationships under the scrutiny of the public eye. In 2019, she began dating her co-star Chase Stokes; their romance lasted almost two years. Later, she admitted that public pressure was one of the reasons for their breakup. Afterwards, she had a brief relationship with comedian Pete Davidson—known for his romances with Ariana Grande and Kim Kardashian—which ended after just a few months.
If his relationship with Cline is confirmed, the grandson of Greece’s last queen, Anna-Maria, will temporarily drop off the list of most eligible bachelors. He first did so in 2022, when he started dating Poppy Delevingne, the model and sister of famed Cara Delevingne. This relationship sparked much gossip at the time. The fact was, Poppy was still legally married and twelve years older than her new partner. However, this love story was short-lived. At the end of 2023, British media reported their split, calling it amicable. Sources close to the couple said they were simply at different stages of life and had parted ways without resentment.
The next woman linked to Tino was another striking beauty—model and influencer Brooks Nader. They were spotted together in June 2024 at Olivia Culpo’s wedding. But the most intriguing part of this story is its Spanish connection. According to recent information revealed by Brooks’s sister, the model may now be in a relationship with none other than Spanish tennis player Carlos Alcaraz. The athlete himself has yet to comment, adding further intrigue to this tangled web of high-profile relationships.
