"The Voice" began its second week of battle rounds Monday night. In addition to the battles, the two-hour episode also featured more behind-the-scenes footage of artists' working with their respective coaches and guest mentors.

To refresh your memory, the coach-mentor pairings are Adam Levine-Ryan Tedder; Blake Shelton-Cher; Christina Aguilera-Ed Sheeran; and Cee Lo Green-Miguel.

The prerecorded episode aired the same day Green pleaded not guilty to giving a woman ecstasy at a Los Angeles restaurant last year.

Here's a rundown of what happened on Monday's show:

Aguilera challenged two of her artists, Josh Logan and Michael Lynch, with a song by Levine's band, Maroon 5: "Harder To Breathe." Green correctly pointed out that Logan's vocals sounded very similar to that of Levine. Levine noted that Logan's voice is more masculine than his. Levine said that while both artists did an amazing job, he favored Logan. Aguilera declared Logan the winner, and Lynch was sent home.

Up next were Team Green's George Horga Jr. and 16-year-old Juhi, who performed Gavin DeGraw's "Best I Ever Had." Shelton said one of his biggest regrets of the season was not pushing his button for Juhi. Aguilera liked Juhi's inflections and Horga's energy. Green said he wanted someone who desperately wanted to win the competition and had no "Plan 'B." He picked Horga, after which Levine swooped in and stole Juhi.

Austin Jenckes and Brian Pounds of Team Shelton were assigned The Bee Gees' "To Love Somebody." The other coaches were unanimous in siding with Jenckes. Shelton thought Jenckes looked passionate about what he's doing. Jenckes advanced, and Pounds was dismissed.

Levine paired James Irwin, 31, with Matt Cermanski, 20. They did a duet of "Counting Stars," by their mentor Ryan Tedder's group, OneRepublic. Levine whoever advanced had work to do to improve. He ultimate selected Irwin. Cermanski got the boot.

Team Aguilera's Destinee Quinn and Lina Gaudenzi covered the Dixie Chicks' "Not Ready to Make Nice." Levine thought both artists came up a little short on the technical front. Shelton believed Gaudenzi performed the song better from start to finish. Aguilera called it an "equal situation," but because she had to announce a winner, she went with Quinn. For the second time in the episode, Levine made a steal, this time with Quinn.

Two of Levine's artists, James Wolpert and Will Champlin - whose dad, Bill Champlin, is a former member of Chicago - closed the show with their rendition of the Imagine Dragons hit "Radioactive." Shelton said Wolpert was a surprise because he "doesn't look the part," citing his geeky appearance.

Nevertheless, he believed Wolpert won the battle. Aguilera disagreed, stating that Champlin was better in her eyes. Wolpert received a vote of confidence from Green. Levine moved forward with Wolpert, and Champlin is now a member of Team Aguilera after she stole him.

The battle rounds resume on "The Voice" today at 9 p.m. ET
