Kara and Corey Britz are siblings.
Kara & Corey Britz's audition in Episode 409 consisted of Kara singing The Police's "Every Breath You Take" while Corey played the guitar. Piers Morgan, Sharon Osbourne, and David Hasselhoff all voted "Yes", sending the duo to the Vegas Round.
After the audition, Corey Britz left the competition after gaining another opportunity. Cara Britz appeared without performing in the Vegas Round. After telling Cara she could have continued into the competition if her brother had not left, they revealed her audition was not strong enough for the judges to send her to the Quarterfinals, eliminating her from the competition in Episode 412.
