Add Page Six on Google Jack Antonoff and Margaret Qualley reportedly quietly separated just a few months before their third wedding anniversary.
The music producer and the actress, who tied the knot in August 2023, first sparked split rumors when Antonoff attended his pal Taylor Swift’s wedding without his estranged wife on July 3.
Now, an insider told People on July 8 that the exes’ relationship had been “rocky” for some time and they were “trying to figure things out.”
Qualley also hinted at trouble in paradise when she changed her Instagram handle back to include her legal name, Sarah Margaret Qualley, instead of her previous handles @isimolady and @isimostar, which referenced Antonoff’s track “Isimo.”
Additionally, the exes haven’t been seen together since earlier this year when they attended the 2026 Grammys.
Page Six is breaking down all the signs pointing to Antonoff and Qualley’s split.
Antonoff and Qualley were last publicly spotted together at the 2026 Grammys in February.
The estranged couple opted out of posing on the red carpet upon arriving at the Crypto.com Arena in Los Angeles.
However, they walked into the venue hand-in-hand and appeared in good spirits as they made their way to their star-studded table.
Qualley turned heads when she didn’t attend Swift and Kelce’s star-studded wedding festivities, including the newlyweds’ rehearsal dinner on July 2.
Instead, Antonoff brought his sister, Rachel, as his date, and the duo was photographed making their way to the dinner hosted at Madison Square in New York City.
Qualley’s absence was rumored to be due to her work schedule on the forthcoming horror film “King Snake,” also starring Drew Starkley.
However, Deumoxi reported that the “Kenzo World” star was spotted at a restaurant in the Big Apple with her dog.

Split rumors heightened when Qualley quietly deleted social media photos of Antonoff from her Instagram, including snaps from their 2023 wedding.
The “Once Upon a Time In … Hollywood” star then unarchived some of the photos, but left the wedding pics off of her grid.
In April, she also changed her Instagram handle from @isimostar to @sarahmargaretqualley23. “Isimo” is notably a track from Antonoff’s band, The Bleachers.
Eagle-eyed fans noticed that the Lana Del Rey x Bleachers track about Qualley titled “Margaret” wasn’t included in the band’s setlist for their “Shadow of the City” tour.
The track is from Del Rey’s 2023 album “Did You Know That There’s a Tunnel Under Ocean Blvd,” and was inspired by the estranged couple’s love story.
