Jack Antonoff had much cause to celebrate after his big wins at the 2024 Grammys, and celebrate he did indeed. In newly shared photos from the producer, he parties with his close collaborators and fellow nominees Taylor Swift and Lana Del Rey as well as poses with Ice Spice, Sabrina Carpenter, Jon Batiste and more at the Grammys and after.

In one of the pictures, posted Tuesday (Feb. 6), Antonoff sticks out his tongue for the camera while the “Anti-Hero” singer, “Munch” rapper and “Butterfly” musician cozy up next to him and producer RIOTUSA. Carpenter, Caroline Polachek and actress Margaret Qualley — the Bleachers frontman’s wife — make appearances throughout his batch of photos, some of which were taken during the ceremony and some of which appear to have been shot at an afterparty.

In a snap from the ceremony, Swift points dramatically at Antonoff’s camera next to a smiling Kelsea Ballerini, with Qualley beaming and Del Rey flashing a peace sign from across their shared table. Another photo finds Del Rey leaning into the frame with a Grammys camera operator; on her own Instagram Story, the “Summertime Sadness” singer explained, “He said he would catch the prettiest shots of me for the telecast.”

Antonoff took home the prestigious producer of the year, non classical golden gramophone at the Sunday (Feb. 4) awards, along with album of the year for his help on Swift’s Midnights. He was nominated in the latter category twice, thanks as well to his production of Lana Del Rey’s Did You Know That There’s a Tunnel Under Ocean Blvd.

The former Fun bandmate is currently gearing up to release his next album with Bleachers, a self-titled project arriving March 8. In September, he dropped the single “Modern Girl,” followed by “Alma Mater” in November and “Tiny Moves” in January. He also shared a music video for the latter track, starring and directed by Qualley.
