Jacquie Roar rocked The Voice season 24 finale with two show-stopping performances!

After rehearsing with her coach, Reba McEntire, the country-rock singer took the stage first with a rollicking rendition of Boston's "More Than a Feeling" that had the coaches and audience on their feet!

"I feel like every time that you get that love and validation, you just keep getting better and better and better," Gwen Stefani raved. "It was so amazing to watch."

Her coach agreed, with Reba raving, "You know that old saying 'Go big or go home?' Girl, you went big! Way to go."

Later in the two-part finale, Jacquie performed her ballad, The Moody Blues' "Nights in White Satin" after an emotional message from her friends and family -- showcasing her softer side with an epic, finale-worthy performance.

"I don't even have words after that," Gwen praised once again. "It was just great and it got better and better... I am amazed by you, that was so beautiful."

"You are a force of nature, it was so pretty," her coach agreed. "It was just a wonderful performance, I'm so proud for you."

Jacquie fought for her place on The Voice live shows every step of the way -- and it paid off. She got a four-chair turn with her Blind Audition performance of Gretchen Wilson's "Here for the Party" and despite losing her Battle Round, was stolen by Reba to later win her Knockout with Maren Morris' "Girl."

During the Playoffs, Jacquie delivered what the coaches declared to be her best performance yet, boldly taking on a classic in "The Chain" by Fleetwood Mac.

"Jacquie came on tonight," Reba marveled after keeping Jacquie for the live shows. "What excites me about Jacquie in the live shows is, she's a show dog -- and she's gonna be a contender."

ET spoke with the coaches on the red carpet ahead of this season's first live show, and all of them marveled at the range of talent they've seen on the show this year.

"The talent this year has just been like, across the board -- all of our teams are pretty insane," Niall raved. "The voices that I have this year are just like, some of the best singers I've ever heard."

John agreed, saying, "The depth of the talent this season is better than I've ever seen it on this show since I've been here."

"This is my eighth season and I've never seen just this level of quality across the board," he continued. "I'm so impressed with our artists this year."

"I have some amazing singers, and I think it's just gonna come down to at this point people start to fall in love with not just the voice, but the person as well," Gwen shared. "It's ridiculous this season. I know we say that every season and it always feels like that, but this one has a particularly tall order."

"I really couldn't tell you [who might win]," Reba agreed.

The Voice's two-part season 24 finale airs Monday, Dec. 18 at 8 p.m. PT/ET and Tuesday, Dec. 19 at 9 p.m. PT/ET on NBC.
