Hilary Duff and longtime boyfriend Matthew Koma have tied the knot.

The star of the upcoming Disney+ reboot of “Lizzie McGuire” wed Koma in small ceremony on Dec. 21.

“The wedding was at her house. It was small and low-key. Only family and close friends,” a source said.

“The ceremony started at sunset and they got married inside the house,” the source continued. “When the ceremony was over, guests cheered. The reception was in a white tent in the backyard. Her sister Haylie was very involved in the wedding prep too. Hilary and Haylie are very close.”

As People notes, Duff’s stylist, Jessica Paster, hinted at the ceremony in an Instagram post, sharing an image of a floral arrangement and writing: “Winter solstice … a day of luv.”
