In a new round of blind auditions on Monday, a powerful singer named Enid Ortiz performed a rousing cover of Adele's "All I Ask."
As the performance went on, it was clear that all four coaches were impressed by her vocal skills, but none of them were committing to turning their chairs.
While Ortiz continued to deliver her powerhouse audition, Gwen Stefani quietly praised the contestant to Shelton, lamenting that Ortiz "deserves to be on" the show.
Shelton listened to Stefani's advice, smacking his button and turning his chair right as the song ended, effectively locking out Stefani, Adam Levine and Alicia Keys and securing the singer a place on Team Blake.
The somewhat sneaky move made a few of his fellow coaches cry foul, accusing Shelton of "cheating."
"That was the dirtiest thing I've ever seen," Levine yelled, standing in front of his chair as Shelton just smiled and gave Ortiz a hug.
"What happened back here is we were all going, 'Is that as good as we think it is?' And I'm like, 'No, that's no good,'" Shelton said, detailing his strategy. "And then [Stefani] looked over to say something to Adam and I [tapped my button]."
"You're sleepin' on the couch tonight," Levine taunted as Stefani and Shelton laughed.
However, Shelton defended his strategy, arguing that everyone had an equal chance to turn around for Ortiz's dynamic performance.
"I know I did some trickery there, but they had the whole song to hit their button," the country crooner argued.
Throughout the season 12 blind auditions, Shelton and Stefani have shown time and again that just because they are dating, doesn't mean they've lost their competitive edge. In fact, their relationship has proven to be a weapon they can both wield against their fellow coaches.
