Carrie Underwood said she had big news that she wanted her fans to hear directly from her. So on Thursday afternoon (Aug. 20), she took to Facebook to share her very big news.

Like so many of her fans had suspected, Underwood will be releasing a new album on Oct. 23. Titled Storyteller, it’s her fifth studio album.

And even better, she revealed some details about the lead single.

"You guys have been the best to me for the past 10 years," she said. "And sincerely, just thank you so much. Secondly and importantly, I want to tell you guys that I have new music! Woo hoo! I have a new song, and it's called 'Smoke Break.'"

Underwood said she wrote it with frequent collaborators (and good friends) Hillary Lindsey and Chris DeStefano, and Jay Joyce produced it.

"It's just kind of one of those story songs that I feel like everybody can relate to about how life is so hectic, and it's so nice if and when you actually get to step away for a second, and we all need that. I really hope you guys love it," she said.

In the decade since winning American Idol, Underwood has sold more than 56 million records worldwide, won seven Grammy awards, had 21 No. 1 singles, and her first four albums -- Some Hearts, Carnival Ride, Play On and Blown Away -- were each certified platinum or multiplatinum.

"Smoke Break" will be available digitally Thursday night.
