Prince Constantine-Alexios of Greece has sparked romance rumours after he was snapped sharing a kiss with American actress and model Madelyn Cline.

Constantine-Alexios of Greece and Denmark, 26, who had previous relationships with Poppy Delevingne and Brooks Nader, was spotted strolling around New York, his arm intertwined with the American actress and model, 27.

Bystanders were quick to capture the moment, with clips then reposted by the social media page, DeuxMoi.

‘Just saw Madelyn Cline with Prince of Greece on Madison Ave,’ one tipster reported, noting, ‘They were like giggling and in sweats,’ as mentioned by Cosmopolitan. 

Speculation about their relationship was further fueled when subsequent videos seemed to capture the pair sharing a kiss at the understated Lion’s Bar in Manhattan’s East Village.

The pair kept the visit low-key. Madelyn, who starred in Outer Banks and I Know What You Did Last Summer,  was seen wearing plain dark trousers, a baseball cap and a t-shirt.

The Greek Prince, arguably one of Europe’s most eligible bachelors, followed Madelyn’s lead, sporting a casual t-shirt and jeans combination. 

The outlet claimed Madelyn’s identity could be confirmed by her choice of footwear. Despite the grainy footage, fans claimed they could detect a unique pair of AirPod Max headphones, which Madelyn was previously seen wearing in a TikTok posted earlier this month.

Photos from inside the restaurant revealed the pair surrounded by other guests, while a later clip appears to show Alexios leaning in for a kiss. 

Rumours were further verified after the Prince shared a photograph on his social media, which fans believe is Madelyn. 

In the photo, she is seen leaning forward, gazing at the pool table in front of her, her blonde tresses falling around her shoulders. 

At the time of writing, neither Madelyn nor the Greek Prince has confirmed or denied their relationship status. 

Alexios, who is reportedly known as Nino to his friends, keeps his life relatively private.

His Instagram account, which has 157,000 followers, is primarily used to share samples of his photography.

The Prince is a native New Yorker who is the grandson of the late King Constantine II, and the eldest son and second child of Crown Prince Pavlos, 58, and Crown Princess Marie-Chantal, 57. 

His mother is the daughter of an American-born British businessman Robert Miller and Ecuadoran beauty María Clara Pesantes Becerra.

Although Greece’s monarchy was abolished in 1973, the descendants of King Constantine II have retained their titles and continue to represent the nation. 

Prince Constantine’s grandfather was the second cousin of King Charles III, and was Prince William’s godfather. Interestingly, the Prince of Wales is Constantine’s godfather.

Constantine attended secondary school in England and graduated from Georgetown University in May 2022.

According to The Australian Women’s Weekly, Tino, as he is known to his friends, is reportedly pursuing a career as a sculptor.    

Alexios spent much of his adolescence in the UK, having attended the prestigious Wetherby School, followed by Wellington College in Berkshire. 

He later returned to his birth country to attend Georgetown University, from which he graduated in 2022. 

As the eldest son of the Crown Prince Pavlos of Greece and Marie-Chantal Miller, Alexios is currently the first in line to succeed his father as the Head of the Greek Royal family. 

His siblings include sister Maria-Olympia, 29, and brothers Constantine-Alexios, 26, Odysseas-Kimon, 20, and Aristidis-Stavros, 17.

Alexios is no stranger to high-profile relationships.

Reports last year hinted at romance between Alexios and the Sports Illustrated star, Brooks Nader, who were spotted packing on the PDA. The pair are thought to have dated between June and July last year.

Before that, Alexios was romantically linked to Poppy Delevingne, whom he is said to have dated between late 2022 and early 2023.

Their romance was brief, with an insider having told Daily Mail that their age gap had been the final nail in the coffin to their relationship. ‘They are just at different stages of their life. There is no animosity,’ the source said.

Meanwhile, the footage has also arrived just over a year after Madelyn ended her high-profile relationship with Pete Davidson, whom she dated between September 2023 and July 2024.

She shared very little of their romance, which only lasted a few months, telling Allure that he had a ‘really cute dog’.

She told Allure last July, ‘The jokes, they write themselves. And I said it before, and I’ll say it again, that is my only comment. He has a really cute dog and some really great girlfriends now.’ 

The model has previously opened up about the hardships of having relationships in the public eye, telling  Jake Shane’s Therapuss podcast, I think at the time I didn’t realise what the repercussions of inviting so many people into – let’s be honest – something that’s intimate.’

The comments were made in reference to her relationship with Outer Banks co-star, Chase Stokes, with whom she spent two years before splitting in 2022.
