Cam Weds Adam Weaver in California

Cam is officially a married woman!

The “Burning House” singer and fiancé Adam Weaver said “I do” Saturday evening (Sept. 24) in Joshua Tree, California, Cam’s rep confirmed to PEOPLE.

The couple exchanged vows in the small desert town in front of 140 guests. The bride, who wore a Jenny Packham gown, walked down the aisle to a mariachi band playing  “Bésame Mucho.”

Their first dance was to Miranda Lambert’s rendition of “Oklahoma Sky.” According to Cam, the song reminds the California natives of one of their very first dates. “It’s just one of the most beautiful songs,” Cam told the publication. “It has such an atmosphere to it. It just pulls you in and both of us loved it.”

The newlyweds treated their guests to a Mexican-themed dinner. They plan to honeymoon in Tokyo and Bali before Cam sets off on her very first headlining tour next month.
