On The Voice's YouTube channel, a video was uploaded Friday of Trainor working with Shelton and his team in preparation for the battle rounds, but also discussing how she backed out of going on her own audition for The Voice, among other stuff like thinking Adam Levine doesn't like her.

Trainor explained that at 18 she was signed to write songs by country publisher Big Yellow Dog. Trainor has written for country acts Hunter Hayes and Rascal Flatts.

It turns out Trainor's publisher at Big Yellow Dog wanted her to audition for The Voice.

"I said 'Absolutely not!'" Trainor revealed.

Trainor said she was "terrified," which is kind of hard to believe considering the success she has found since dropping All About That Bass.

She said she was afraid of the coaches and admitted that Levine "scares" her still.

Trainor performed during Season 7 and dished she was "terrified".

"I don't know if he likes me," Trainor explained to Shelton, adding, "Can't figure it out."

"Here's the thing about Adam," Shelton said, adding, "He likes everybody a little less than he likes himself.

"That's across the board, so you're good," Shelton dished to Trainor.

Tune in on Mondays and Tuesdays starting at 8 p.m. ET for Season 8 of The Voice on NBC.
