Reba agrees, praising Mara's vocals and calling her performance "an emotional roller coaster of excitement."

"I think people just saw a different side of your voice," her former coach marvels. "This was your best moment on the show."

As for her current coach, Niall bemoans the fact that Mara's performance has made his Playoff decision that much harder.

ET spoke with Gwen ahead of this season's Battles, where she opened up about how surreal it is to return to The Voice without hubby Blake Shelton by her side. The Cowboy departed the NBC singing competition earlier this year, after 23 seasons.

"It feels kind of like [my] first season, before I knew he existed," she shared. "It's kind of weird, but it's also like, I'm having so much fun."

"Like, I'm only here because it's fun," Gwen added. "The coaching and actually getting to know your team after the Blinds is my favorite thing, 'cause it's like, the dream's there."

She admitted, however, that it is a little nerve-wracking to look to Blake's chair and instead see The Voice's newest coach -- the Queen of Country herself.

Of how Reba's handled her first season so far, Gwen recalled the Blind Auditions with a laugh.

"She did great. She didn't have to do anything," she remembered. "She'd be like, 'I think you were great. I'd love to have you on my team,' and then they'd be like, 'I pick you!'" 

The Voice airs Mondays at 8 p.m. PT/ET and Tuesdays at 9 p.m. PT/ET on NBC.
