Coach Blake Shelton told Huston she looked like a superstar.

Coach Christina Aguilera told her it was the most confident she’s ever seen her.

And Huston's coach, Pharrell Williams, told America the preschool teacher who -- before her audition for the NBC hit reality show sang “once or twice a year� -- should move forward in the competition.

Huston, the 25-year-old Grand Island native who teaches preschool at Lincoln's Arnold Elementary, said in a clip that aired before her "Top 9" performance that it was bittersweet to be the last member of Team Pharrell.

Last week her fellow team member Daniel Passino was sent home.

“But it makes me want to work harder,� she said.

Williams said when Huston turns down the volume, it’s “super emotional,� and he asked if she could relate to the lyrics about unrequited love.

“Sometimes,� she said. “Everyone’s had that time in your life when someone hasn’t been as responsive as you want them to be.�

Williams told her she had to treat this performance as her courthouse and speak her piece.

In a flowing white jumpsuit, she seemed to convince the judges.

“That was my personal favorite by you this entire season,� Shelton said. “Superstardom looks good on you.�

Aguilera told Huston her performance was a good balance of being bold, and tender and vulnerable where it counted.

“This is by far the favorite thing I‘ve seen from you,� said Aguilera, who’s made few comments on Huston’s performances. “I could see the confidence in yourself. I’ve been waiting for a while for you to own that great big voice.�

Williams told Huston her dynamics told a story and that her performance was both intentional, "super delicate" and tender.

“The word I would say is graceful,� he said.

On Tuesday's show, performers will see who America votes through to the next live round.
