The Backstreet Boys are back with the "Into the Millennium" Las Vegas residency at the Sphere and a new song, which dropped Friday.

Las Vegas Residency shows are set to be held from July 4, 2025, to November 15, 2025, at the Colosseum at Caesars Palace in Las Vegas, Nevada.

The 90-minute show was classic Shelton, as he rattled off hit after hit from his deep catalog, sipped booze from a plastic black cup on stage and often bantered with the crowd. During one moment, he noticed a fan’s custom-made t-shirt that said: "Still not a Swiftie. I’m a Sheltie.”
