The demure 18-year-old singer from McKinney, Texas, fizzled Wednesday with her rendition of "Flashdance" by Irene Cara during an evening of 1980s tunes on the Fox talent competition. After her performance, "Idol" judge Jennifer Lopez warned Cavanaugh to stop listening to everyone and "let it go" when she's performing on stage.
The panel also wasn't in love with Elise Testone's take on "I Want to Know What Love Is" by Foreigner. Randy Jackson told the 28-year-old teacher from Charleston, S.C., that she's "much better than this."
Between the individual performances, the eight remaining finalists paired up for male-female duets.
One of the singers will face dismissal Thursday.
