The Backstreet Boys gave fans a sneak peeks at what their Las Vegas residency will look like when they took the stage at the iHeartRadio Music Festival for a surprise performance on Saturday.
The boy band rocked the T-Mobile Arena in Las Vegas, Nevada, performing some of their biggest hits from the last two decades in an unannounced appearance that sent fans into a frenzy.
Nick Carter, A.J. McLean, Kevin Richardson, Brian Littrell and Howie Dorough performed a short set of their own hits, and were then joined on stage by country stars Tyler Hubbard and Brian Kelly of Florida Georgia Line for an epic rendition of their 1997 smash hit "Everybody (Backstreet's Back)."
