In episode 3 of NBC’s increasingly popular TV show, ‘The Voice’, coach Cee Lo Green brings on multi-platinum, Grammy winning R&B Diva Monica to help him train his team for the big battles round.

Christina Aguilera paired up vocalists Tarralyn Ramsey and Frenchie Davis to do battle with Beyonce’s “Single Ladies”. Neither of the ladies were thrilled with Xtina’s decision since it meant one of them would be going home afterwards.

The Voice’s opening week’s gimmick was the blind auditions. With that over, it’s time to move on to the battle round!

Each of the coaches paired up two of their team members and had them face off in a duet of a popular song. Then, while the other coaches could weigh in, it was up to the singers’ coach to eliminate one of them.

Adam Levine didn’t hesitate to call Vicci Martinez and Niki Dawson on Pink’s ‘Perfect’ “by far the best duet of the night.” The coaches were shocked Cee Lo Green paired the two as that meant he would have to lose one from his team.

!!SPOILER ALERT!!
