Darci Lynne Farmer saved her best performance for last!
Throughout this season of America's Got Talent, Farmer has become one of the show's fan favorites for her amazing ventriloquism, comedic timing and pitch perfect singing voice that allows her to hit flawless high notes, even with her mouth closed!
However, on the first night of the America's Got Talent finals on Tuesday, Farmer outdid herself with an epic duet between two of her most popular puppets.
The 12-year-old hopeful hit the stage along with her rabbit friend Petunia -- the puppet that earned her the Golden Buzzer from Mel B in the first episode of the season -- and her mouse friend Oscar, who famously serenaded the former Spice Girl star later in the season.

Flawlessly switching back between both Oscar and Petunia's voices, Farmer showed just how masterful she really is with her talent, and when the puppets broke out into a duet of The Beatles "With A Little Help From My Friends," it was almost impossible to believe what she was able to do.

"You are just hands down incredible," Mel B marveled. "You're 12 years old, you're self-taught, you were so shy, and look at you now! I've said this from the very beginning: You could win this."

Heidi Klum couldn't have agreed more, telling Farmer that she has "that special something" that makes a star, and that she "might have just won $1 million" with her amazing final act.

"The best part of doing this job is when you are there and you can say, 'I was there at the beginning of someone's career and I witnessed a star,'" Simon Cowell praised. "Tonight, again, I've just witnessed a star emerge, because that's what you are. You're special, incredible, funny, talented and I think you're going to win."

To see if the judges' predictions come true, fans will have to tune in to the America's Got Talentfinals results show on Wednesday at 8 p.m. ET/PT on NBC.
