Carrie Underwood was the sole country music performer during Tuesday night's (Oct. 9) 2018 American Music Awards ceremony. The country star performed her new song "Spinning Bottles."

Underwood co-wrote "Spinning Bottles" with David Garcia and Hillary Lindsey. The song appears on her new album, Cry Pretty, which was released in mid-September, and is about a woman who is in a relationship with an alcoholic.

"This ain't a game / Nobody wins," Underwood sings in "Spinning Bottles." "Yeah, nobody gets lucky when that bottle spins / Again and again, again and again, again and again ..."

Underwood's trip to the 2018 American Music Awards was her first awards show appearance since announcing her second pregnancy. In November, she will be co-hosting the 2018 CMA Awards, with Brad Paisley, for the 11th consecutive year; later this month, she'll be honored at CMT's 2018 Artists of the Year event as well.

Underwood was a 2018 American Music Awards nominee for Favorite Female Artist -- Country. Her fellow nominees included Kelsea Ballerini and Maren Morris; Underwood won the category, and was presented the honor by Thomas Rhett and actress Sara Gilbert.
