The Voice season 7 judges Adam Levine, Gwen Stefani, Pharrell Williams & Blake Shelton with host Carson Daly.

The second week of battles began on The Voice on Monday, filled with matches not only of the singers, but also the coaches. Particularly, Gwen Stefani.

The No Doubt breakout (who previewed the music video for her latest single, "Baby Don't Lie," after the episode) previously found herself in showdowns with Blake Shelton during the blind auditions, and kept sparring with Adam Levine throughout Monday night's battles.

Though she has perfected the art of the last-second button-push and even started singing the opening lines of her "Hollaback Girl" hit, Levine walked up to the contestant's family in the audience and shouted, "Don't betray your family!"

The episode of sudden-death duets were aided with guest mentors: Stevie Nicks to Levine, Little Big Town to Shelton, Alicia Keys to Williams, and Gavin Rossdale to Gwen Stefani.
