See Jack Antonoff at Taylor Swift Wedding Amid Margaret Qualley Breakup

Jack Antonoff had a front row seat at Taylor Swift and Travis Kelce’s forever. 

Days before Margaret Qualley and the Bleachers frontman reportedly split following three years of marriage, Antonoff stepped out without his wife to support the “Style” hitmaker—his longtime collaborator—as she tied the knot with the NFL star at Madison Square Garden July 3. 

Though he attended the event without The Substance star by his side, Antonoff—who donned a black tuxedo with a white button-down shirt underneath—didn’t fly solo to the nuptials. Indeed, he made the occasion a family affair as his sister Rachel Antonoff stood in as his plus-one.  

For the Manhattan I do’s, she opted for a silver gown featuring all-over sequins. The pair also attended Swift and Kelce’s rehearsal dinner together July 2. 

Qualley, 31, and Antonoff, 42, separated just one month shy of their third wedding anniversary, according to People, who cited multiple sources. In addition, Qualley previously cleared her Instagram profile of photos featuring the couple’s wedding, though she has since unarchived a few select pics.

E! News has reached out to Antonoff and Qualley’s reps for comment but have not yet heard back.
