Season 10 of "The Voice" hasn't even debuted yet, but there's already a standout star among the contestants.

And she's a familiar star.

A new sneak peek from the upcoming season reveals that Alisan Porter — who made a name for herself in the '90s as the cherub-cheeked child actress from the big-screen dramedy "Curly Sue" — can really sing.

In fact, Porter's blind audition performance of the Linda Ronstadt hit "Blue Bayou" inspired all four "Voice" coaches — Adam Levine, Pharrell Williams, Christina Aguilera and Blake Shelton — to turn their red seats in her direction, and then get out of those seats for a standing ovation.

"I was an actress when I was very young," Porter, who also appeared in the Steve Martin flick "Parenthood," told them. "It's not my passion. This is my passion."

They could tell.

"That was the most beautiful, flawless, passionate, pitch-perfect thing I have ever heard in my entire life," Levine told her as he urged her to join his team. "I'm astonished by you. ... You're going to win 'The Voice,' and I believe you can do it on my team."

But, of course, they all wanted her for their teams. After some careful consideration, she ... made a decision we'll have to tune in to see for ourselves!

Season 10 of "The Voice" kicks off Feb. 29 at 8 p.m. ET on NBC.
