Country music's greatest put on their best boots for the 60th annual American Country Music Awards on Thursday (May 8) in Frisco, Texas, including timeless super group Rascal Flatts!

The "Bless the Broken Road" standouts were joined by '90s heartthrobs the Backstreet Boys for a genre-blending performance of epic proportions, unlike anything the ACM stage had ever seen!

The star's turned the award show into a party, singing, 2006's "What Hurts The Most," 2025's "I Dare You" (a Jonas Brothers collab), The Backstreet Boys' 1999 hit, "Larger Than Life" (showing off their best boyband dance moves), and, of course, 2006's "Life Is a Highway."

The groups flawlessly delivered each track in unison, reviving the spirit of Y2K and combining the best features of each genre into an unforgettable closing moment.

Rascal Flatts are gearing up to release an album of collabs titled Life Is A Highway: Refueled Duets, slated to hit airwaves next month.

The highly anticipated record will feature 10 reimagined Rascal Flatts tracks with a little help from Jason Aldean, the Jonas Brothers, Blake Shelton, Kelly Clarkson, and more!

Blake Shelton, Little Big Town, Lainey Wilson, Chris Stapelton, Cody Johnson, Jelly Roll, Zach Top, Brooks & Dunn, Alan Jackson, Megan Moroney, Kelsea Ballerini, Reba McEntire, Ella Langley, Miranda Lambert, Clint Black, LeAnn Rimes, Wynonna Judd, Dan + Shay, Shaboozey, Brothers Osborne, and Sugarland also stole the show at this year's anniversary show.
