Madelyn Cline can’t keep her lips off Prince Constantine-Alexios of Greece and Denmark.

The new couple was seen packing on the PDA — again — in a steamy new snap.

Deuxmoi posted the photo in question via Instagram Sunday, captioning it, “💋 The People’s Princes.”

The image was a close-up shot of Cline, 27, and Constantine-Alexios, 26, making out in a crowded space.

The two appeared deep in the moment, paying no mind to the various people around them — one of whom even photobombed.

The actress wore her dirty-blond hair down and held back with a thick black headband, while the royal was dressed in a light gray T-shirt.

To make the kiss more passionate, Cline had her hand around Constantine-Alexios’ neck.

The couple’s blossoming romance first captured attention last week after Deuxmoi shared a photo of them kissing at the Lion’s Bar, located in Manhattan’s East Village.

Both were casually outfitted; the “Outer Banks” actor wore a T-shirt, dark trousers, and a tan cap, while the artist chose a light tee and jeans, with a sweater in his hands.

Once more, they seemed unafraid of public displays of affection as they kissed right at the restaurant’s entrance, drawing the curious gazes of nearby diners.

Deuxmoi also obtained a video of Cline and Constantine-Alexios holding hands as they walked down a sidewalk in New York City.

The outing seems to have been on a different day, as they were in different clothes in the clip.

The “Glass Onion” star previously dated comedian Pete Davidson from September 2023 to July 2024, with a source claiming at the time of their split that it was “amicable.”

As for Constantine-Alexios, he had a brief fling with model Brooks Nader, with whom he attended Olivia Culpo and Christian McCaffrey’s June 2024 wedding.
