American Idol and singing career
On October 30, 2002, the reality TV singing competition American Idol held auditions in Nashville, Tennessee for the show’s second season. Locke successfully passed through to the next round, and in December was chosen to perform on the show. She finished third, behind winner Ruben Studdard and runnerup Clay Aiken. She has since been invited back to the show to perform twice (seasons 3 and 7).
