NBC's 'The Voice' will gain an additional country music representative when Reba McEntire joins the show as an adviser alongside coaches Blake Shelton, Christina Aguilera, Cee Lo Green and Adam Levine during the "battles" phase of the competition.

She won't be coming alone, though. Reba will be joined by R&B hitmaker Monica, Aussie pop singer Sia, and acclaimed music producer Adam Blackstone.

The new advisers will be along for the ride during the "battles" segment of the reality singing competition, which will be a four-episode run. In these episodes, contestants from each team will duet and the weakest one will be sent home. But first, the celebrity coaches must add more players to their team during a two-hour auditions show on May 3.

Naturally, McEntire will lend her sage advice to her fellow country star Shelton directly, while Monica and Green will buddy up, Sia will assist Aguilera, and Levine will rely on Blackstone.

You can catch more of 'The Voice' blind auditions on Tuesday at 9PM ET -- pick your favorites now so that you can watch the contestants grow musically throughout the summer. Starting in June, 'The Voice' will boast live shows.
