Derek Blasberg’s famous friends came out in style to help him celebrate his birthday!

The fashion writer and socialite, who turned 42 last month, celebrated the milestone — as well as Kate Hudson and jewelry designer Jennifer Meyer’s birthdays — at a starry bash at New York City’s En Japanese Brasserie on Saturday, May 4.

Among the stars spotted arriving at the soirée were Kris Jenner and her boyfriend, Corey Gamble, as well as Jeff Bezos, who was accompanied by his fiancée, Lauren Sánchez.

Hot off of the premiere of her latest film The Idea of You, Anne Hathaway arrived hand-in-hand with her husband, Adam Shulman.

Blasberg’s longtime pal Karlie Kloss also attended, along with Emily Ratajkowski, influencer Emma Chamberlain, model Joan Smalls, as well as actresses Eiza González and Jemima Kirke.

Former J.Crew executive and Real Housewives of New York City newcomer Jenna Lyons also attended the N.Y.C. party. She arrived holding hands — and wearing matching jackets — with girlfriend Cass Bird.

The guest list also included Andy Cohen, Paul McCartney’s grandson Arthur Alistair Donald and Lil Nas X — perhaps the most important attendee, per Blasberg.

In an Instagram Stories post, the writer shared a photo of himself with the “Panini” rapper and wrote that “all I wanted for my birthday was physical contact with” him.

Also on Instagram, Blasberg documented the joint celebration with a photo carousel, revealing that Demi Moore and Jake Gyllenhaal also were present for the festivities.

Blasberg shared more party details in the caption of his birthday post, starting with the menu.

“PRO-TIP. Best cure for birthday blues: Tequila, fried chicken, and cake. (Coincidentally, also my three favorite food groups!),” he wrote.

“Last night, I celebrated my 42nd birthday with @patron and @enjapanesebrasserie,” the writer continued, adding that he “probably had too fun naming the speciality cocktails: ‘Meet me in San Luiz Margarita’ and ‘Bo Derek Blitz Spritz’ — some of my best work.”

The socialite finished by thanking everyone who contributed to the star-studded event — and “everybody who came out to celebrate little ole meeeeee.”
