Kimberly Caldwell is officially off the market.

The former American Idol finalist wed fiance Jordan Harvey on New Year's Eve, which was Wednesday night, in an outdoor desert ceremony at the Bougainvillea Estates in Palm Springs, E! News reported.

The following day, the 32-year-old singer posted a wedding photo on Instagram which featured the couple smiling and intimately touching heads. Caldwell was pictured gently grasping onto her husband's arm.

"Best day of my life. @jordancharvey #JKNYE photo by @xxtherogxx," Caldwell captioned the image.

Caldwell wore a strapless, mermaid-style gown by Walter Mendez, according to E! News, in addition to a small veil. Harvey sported a black bow tie, burgundy suit with a white rose on the lapel, and a white shirt. Caldwell painted on a maroon lip to match her husband's attire.

In 2003, Caldwell finished American Idol's second season in seventh place. The singer went on to host the first season of Best Ink on Oxygen in 2012.
