Why did Margaret Qualley and Jack Antonoff split up?

Margaret Qualley and Jack Antonoff are separating after nearly three years of marriage, People reported Wednesday. The news sent shockwaves throughout the entertainment industry, as Qualley is an Oscar-nominated actress while Antonoff is a Grammy-winning producer.

Rumors of their breakup began circulating after Antonoff, 42, attended Taylor Swift and Travis Kelce's wedding without Qualley. Antonoff brought his sister, fashion designer Rachel Antonoff, instead. Qualley, 31, also deleted photos from her wedding on Instagram.
