Anthony is currently engaged to his Hamilton costar Jasmine Cephas Jones. The two met during a table read for the musical in 2015 and began dating shortly after. Four years later, Anthony popped the question in front of her mother, his grandmother, and pal Cynthia Erivo. When asked about their wedding plans, Anthony told Vogue in 2019 that "the DJ's gotta be on point." He added, "I want people sweating, suit jackets off, chancletas on."
