In an unprecedented twist, both mentors were obligated to immediately eliminate one of their mentees at the end of the night – but not before taking the stage to perform with their team.
Spoiler Alert: Keep reading to find out which contestants made the cut and who was sent home.
"I didn't see this coming," Shelton admitted at the start of the show, upon learning of the instant elimination requirement. "I think it's caught us all off guard a little bit. ... It sucks."
An Upsetting Twist"I'm really upset right now about it, because at this point I strongly believe in my team, and they're all winners to me," Aguilera told host Carson Daly about the rule. "It's going to be super, super tough to make this decision tonight."
From Team Blake, teen country sensation RaeLynn performed a rendition of Jason Aldean's "She's Country," prompting Shelton to say: "This is the most proud moment I've had this whole season. ... You just proved to America that country can kick ass."
And though Aguilera called RaeLynn "a little badass," it was Team Blake's Jermaine Paul whom she dubbed her "favorite," after his rendition of Phil Collins's "Against All Odds."
Shelton agreed, saying he believed the performance would be a "turning point" for Paul.
From Aguilera's team, Ashley De La Rosa, who was celebrating her 18th birthday, powered through a rock version of Jewel's "Foolish Games." After her performance, Shelton said that Aguilera saving De La Rosa a couple of weeks ago was "the smartest decision that's been made this year."
Judges Take the StageShelton and Aguilera also each took the stage with their four remaining team members, with Team Christina performing Aguilera's hit "Fighter," and Team Blake tackling the Eagles's "Heartache Tonight."
And they weren't the only judges to perform. Though his team won't face off against Team Cee Lo until next week, Adam Levine joined his Maroon 5 bandmates on stage – along with Wiz Khalifa – to debut their new single, "Payphone."
When it finally came time for the eliminations, both Shelton and Aguilera struggled with their decisions.
"I was really hoping for somebody to come out here and not do a good job ... and it just didn't happen tonight," Shelton said, before opting to eliminate Jordis Unga based on audience votes two weeks ago that placed her in the bottom three.
And, in a somewhat shocking move, Aguilera elected to let Jesse Campbell go.
After Campbell's performance of Beyoncé's "Halo" earlier in the evening, which he dedicated to his daughter, Levine told him he was a "huge, huge favorite" to win the entire competition.
Audience votes announced on Tuesday's episode of The Voice will determine which of the remaining six contestants from Team Christina and Team Blake will stay in the competition.
