“I feel like when we wrote this song ‘Spinning Bottles’ we kind of each had people in our heads go through this,” she said of the track. “It’s hard to write, it’s hard to get it out, it’s hard to say it’s gonna go on the album … It’s difficult to sing it to the world, but its life; that’s a part of life. It’s hard to just put yourself out there like that.”

Underwood added: “Your’e just going into a writing session letting your feelings out and just hope people get it.”

Underwood’s glam AMAs appearance comes two months after she announced she’s expecting her second child with husbandMike Fisher, with whom she already shares 3-year-old son Isaiah Michael.

The country star opened up about her expanding family on the AMAs red carpet pre-show — and son Isaiah’s reaction!
