While the "So Yesterday" singer has been candid about most of her relationship with Koma, the wedding news was kept well under wraps and the guest list only comprised of "family and close friends."
"The ceremony started at sunset and they got married inside the house," a source told People. "When the ceremony was over, guests cheered. The reception was in a white tent in the backyard." The outlet further reported that sister Haylie Duff was very involved in the months leading up to the wedding.
"Her sister Haylie was very involved in the wedding prep too. Hilary and Haylie are very close," the source added. Both Duff and Koma announced their engagement a month after the proposal in separate Instagram posts earlier this year.
