As the blind auditions for "The Voice" season 13 come to a close, the coaches are now preparing their teams for battle. Following tradition, they invited an all-star group of advisers to help their artists win the fight of their lives.

New coach Jennifer Hudson is bringing in Destiny's Child founding member and four-time Grammy Award winner Kelly Rowland, who was seen giving her all to train Hudson's team.

Multi-platinum selling country music trio Rascal Flatts is coming in for Blake Shelton. The teaser shows them packing in laughter as much as lessons for the starstruck artists.

Miley Cyrus invited no other than her own father, "Achy Breaky Heart" singer-songwriter Billy Ray Cyrus. Together they will coach an all-girl team, after Miley made "herstory" earlier this week for being the first coach ever in "The Voice" to create a team made up of only one gender.

Platinum selling singer and actor Joe Jonas completes the group of advisers by joining Adam Levine's team.

Fans can expect a lot of action in the upcoming episodes, as the teaser hints of amazing battles coming around. Levine was even heard saying, "This has got to be the best battle that we ever had."

In the Battle Rounds, the coaches will pit two of their team members against each other to sing a duet. The challenge for the contestants is to sing their hearts out in able to stay in their teams. However, those who will not be chosen would still get a chance to remain in the game. That is, if they get stolen by any of the other coaches, who would have two steals each.

In the meantime, fans are clamoring for the return of season 12 judge Gwen Stefani, who in past years have shown great chemistry with the other coaches, especially with his boyfriend Shelton. She did admit that she would be willing to come back in season 14, but no word yet from NBC on whether this would actually happen.

She still has a chance though, with one seat still vacant for next season. As of press time, the confirmed judges for "The Voice" season 14 are Shelton, Levine, and "American Idol" season 1 winner Kelly Clarkson.

"The Voice" airs Mondays and Tuesdays at 8 p.m. EDT on NBC.
