The 31-year-old Younger star and singer revealed on Thursday that she and longtime partner Matthew Koma, with whom she shares 6-month-old daughter Banks, had gotten engaged.
“He asked me to be his wife♥️,” she wrote on Instagram, alongside two photos of the two, with her showcasing a large diamond engagement ring.
“I asked my best friend to marry me… @hilaryduff,” Koma wrote on his own Instagram page, alongside the same pics.
Neither star gave details about the proposal but they did geo-tag their posts “New York, New York.”
This will mark the second marriage for Duff, who in 2016 finalized a divorce from hockey player Mike Comrie after six years of marriage. The two share a 7-year-old son, Luca.
