See Photos from Inside Poppy Delevingne's Birthday Party, Including Pics with Celeb Friends Like Gigi Hadid!

Poppy Delevingne celebrated her 37th birthday last weekend with a party in New York City and we have photos from inside the event!

The English model and socialite was joined by celeb pals for a night of dancing at Loosie’s at Moxy Lower East Side on Wednesday (May 3).

It was a joint birthday party for Poppy and her friend Derek Blasberg, who was one of the red carpet co-hosts at the Met Gala just days earlier. Inside the party, she toasted with Della Vite Prosecco Superiore DOCG, from the prosecco range Poppy co-founded with sisters Cara and Chloe.

Other celebs in attendance included Gigi Hadid, Edward Enninful, Amber Valletta, Georgia Fowler, and Poppy’s new boyfriend, Prince Constantine Alexios of Greece.

Poppy wrote on Instagram, “A few days late, but… this is… 37 *gulp 🎈. Thank you to all my magical friends & NYC family who made it SO special… (@thelsd 👑) & @loosiesnyc for the sore feet & weary heads the next day. LOVE YOU ALL, *truly madly deeply 💘.”

FYI: Poppy is wearing a Halston dress.
