Poppy Delevingne got cozy with Prince William’s godson during her star-studded 37th birthday party Wednesday night.
The older sister of Cara Delevingne was spotted “cuddled up” with Prince Constantine Alexios of Greece and Denmark during her intimate soirée at hotspot Loosie’s inside the Moxy Lower East Side hotel in New York City, an insider tells Pvnew exclusively.
Poppy was “smiling ear to ear all night” and looked “ecstatic” to have Constantine, 24, by her side, the source shares, adding that the bash had “amazing vibes.”
The birthday girl, dressed in a vintage Halston cream dress, and the royal were also seen hitting the dance floor under a disco ball chandelier.
Guests at the exclusive fête included Gigi Hadid, Derek Blasberg, Edward Enninful, Amber Valletta and Georgia Fowler.
“Everyone was on the dance floor, Gigi included, ’til a little after 3 a.m.,” the source tells us. “The party was so private and intimate. Everyone felt like they could let loose.”
We hear Poppy was presented with a cake as guests toasted to her birthday with her Della Vite prosecco. She then had her friends taste the brand’s new rosé, which has yet to be released.
Poppy launched her prosecco line with her two sisters, Cara Delevingne and Chloe Delevingne, in 2020. Both of her siblings were absent from the party for unknown reasons, though Cara, 30, had just been in the city to attend the 2023 Met Gala two days prior.
We’re told Poppy and Constantine, known as Tino amongst friends, have been dating for nearly seven months.
They first sparked romance rumors this winter when they were spotted out and about together multiple times, starting with a hand-in-hand stroll through London in February.
Constantine seemed to confirm their romance when he reportedly posted a photo of Poppy on Instagram in March.
Poppy married James Cook in May 2014, but the Daily Mail reported in January 2022 that they had been separated “for the best part of a year.”
While neither party has directly addressed the rumored breakup, the socialite was spotted without her wedding ring in February 2022, while Cook appeared to have a profile on the exclusive dating app Raya in November.
Constantine is the eldest son and second child of Crown Prince Pavlos and Crown Princess Marie-Chantal of Greece. As a grandson of Constantine II and Anne-Marie of Denmark, who were the last king and queen of Greece, he is a member of the non-reigning Greek royal family.
William, 40, famously attended Constantine’s christening in 1999 when the Prince of Wales was just 16.
Poppy’s rep did not immediately respond to our request for comment.
