Christina Aguilera, Cee Lo Green, Adam Levine and Blake Shelton are the celebrity judges for the series, who do not see the contestants while they perform their audition song. If one of the judges likes a contestant, he or she presses a button that rotates the judge's chair to face that contestant. If only one judge presses the button, the contestant will automatically become a team member for that judge (each judge will eventually have eight members on his or her team). However, if more than one judge presses the "I Want You" button, then the contestant gets to choose which judge he or she would like to be mentored by.

Davis, who performed "I Kissed a Girl," was selected by Aguilera and is now a member of her team. Following her performance, a beaming, emotional Davis told the viewing audience to never give up on their dreams.

A finalist on the second season of "Idol," Davis has starred on Broadway in Rent and in tours of Dreamgirls; Sing, Mahalia, Sing; and Ain't Misbehavin'. She also played the Fairy Godmother in Cinderella at Berkeley Playhouse.

The next episode of "The Voice" will air May 3 at 9 PM ET on NBC. Carson Daly hosts.
