'The Voice' Contestants Shine Their 'Lights' As Battle Rages On

Team Adam's Melanie Martinez and Caitlin Michele give a soulful rendition of Ellie Goulding's 'Lights' during the second round of battles.

"The Voice" contestants were ready for combat as the battle rounds continued, with the sparring even more exciting thanks to the "steal."

The night offered up a few surprise winners as celebrity coaches [artist id="1350855"]Adam Levine[/artist], [artist id="1163841"]Cee Lo Green[/artist], [artist id="509026"]Christina Aguilera[/artist] and [artist id="1164298"]Blake Shelton[/artist] became more strategic with their rosters. They offered little help to their fellow mentors in deciding whom to keep and whom to lose, in case, you know, they wanted to swipe the loser for their own.

Surprise Package

Cee Lo was looking for the best singer/ dancer package when he paired country boy Cody Belew with city girl Domo. "Bam Bam" Belew had clear disadvantages during rehearsals against the dancer who exuded charisma. When the duo hit the stage, though, both held their own with Domo's beauty outshining Belew by a hair. In the end, it came down to personal preference and, in a surprise move, the usually smitten Cee Lo chose to keep Belew.

Smooth Undertaking

Young met "old" on as 15-year-old Nathalie Hernandez of Team Christina faced off against 24 year-old Aquile. It was a battle of the ages, indeed; Aquile's smooth, controlled R&B sound was proof of his experience, but Hernandez impressed the judges with her raw talent and tone that was reminiscent of Joss Stone. "When I was fifteen, I was a zit," Levine told the young singer, just before their coach Xtina chose Aquile to stay on.

"Lights" Shine Bright

Team Adam's Caitlin Michele and Melanie Martinez managed to pull off the most emotional performance of the night with an indie rendition of Ellie Goulding's "Lights." Guest mentor [artist id="854"]Mary J. Blige[/artist] was taken aback by Martinez's "depth" during rehearsals. Somehow, the polarity between the powerful and theatrical Michele worked with Martinez's raw breathiness, and the performance left Levine "over the moon." It also meant a tough decision for the handsome coach who went with his gut and chose Martinez. But it wasn't over for Michele. Shelton and Green both pushed their buttons to steal her up, but her over-the-top persona felt more at home with the over-the-top Mr. Cee Lo Green.

Recap (winner vs. loser):

Team Cee Lo: Cody Belew vs. Domo

Team Christina: Aquile vs. Nathalie Hernandez

Team Adam: Melanie Martinez vs. Caitlin Michele

Team Blake: Rudy Parris vs. Charlie Rey
