According to People, the country star was approached by FOX to be a guest judge on American Idol for the Chicago auditions, taking place on August 30 and 31.
The singer is filling in for Paula Abdul, who recently announced her resignation after eight seasons on the show. Twain will be part of the panel of judges, including Simon Cowell, Randy Jackson and Kara DioGuardi, and will help choose which aspiring singers will make the cut.
The Canadian is following in the footsteps of other celebrity judges invited on the show, including Victoria Beckham, who sat in as judge at the Boston auditions, and Mary J. Blige, who was guest judge yesterday (August 17) in Atlanta.
