Fans can purchase tickets for all upcoming Backstreet Boys Sphere shows on sites like Vivid Seats; the official on-sale is Friday, Feb. 21. Vivid Seats is a secondary market ticketing platform, and prices may be higher or lower than face value, depending on demand.

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.”

The Backstreet Boys will be heading to Las Vegas for a summer residency at The Sphere, here's how to get tickets.
