Carrie Underwood has her share of memorable moments at the ACM Awards over the years, including 2011's 'Undo It' duet with Aerosmith frontman Steven Tyler. However, the Oklahoma native suggests that this year's performance might be the best -- and most surprising -- yet.

"Being in Vegas is always a lot of fun, and I'm glad to finally get to perform 'Good Girl' in a big situation," the singer says (quote via CMT). "It's gonna be really good. We're having something made for the performance, and it'll be pretty rockin'."

The 29-year-old, who is nominated for two trophies -- Top Female Vocalist, and Vocal Event of the Year with Brad Paisley for 'Remind Me' -- will release her highly anticipated album, 'Blown Away,' on May 1. The first single, she hints, is indicative of what fans will find on the entire CD.

"I have always been a fan of songs that have attitude, but the ones I'm talking about have a darker storyline," she told Entertainment Weekly. "It seemed to be what the album wanted, so I decided to roll with it."

Other performers for the ACM Awards include Blake Shelton, Lady Antebellum, Jason Aldean, Luke Bryan, Miranda Lambert and more. See our Top 10 reasons for tuning in to the ACMs here.

The 47th annual ACM Awards will air live from the MGM Grand in Las Vegas, April 1 at 8:00 PM ET on CBS.
