The singer weds therapist fiancé Josh Hartzler at her family's home in Arkansas

Evanescence singer Amy Lee was married on May 6, her rep confirms to PEOPLE.

Lee, 25, married Josh Hartzler, a 29-year-old New York City-based therapist, at her family’s home in Little Rock, Ark., the Arkansas Democrat-Gazette reported Wednesday.

According to the paper, Lee’s grandfather Bob Cargill performed the ceremony, and Hartzler’s friend (and former Evanescence member) David Hodges was a groomsman. The guests included Evanescence guitarist Terry Balasamo.

Lee announced her engagement on Jan. 9 during a taping of an hour-long special for Canada’s MuchMusic network. When the host commented on her ring, the singer replied, “I got engaged last night.” She said her fiancé got down on one knee: “It was awesome.”

At Saturday’s 1 p.m. ceremony, Lee wore an ivory Victorian-style dress and veil, the Democrat-Gazette reports. The reception featured a robin’s-egg-blue wedding cake – a white-chocolate butter cake colored blue with coconut filling and cream-cheese icing.

According to the paper, the newlyweds spent their wedding night at Little Rock’s Peabody Hotel before leaving for a honeymoon on an island south of the Bahamas.
