The Backstreet Boys have extended their "Into The Millennium" residency at the Sphere in Las Vegas, adding three New Year shows on 31 December, 1 January and 2 January. This marks the second consecutive year the group will see in the new year at the venue, underlining the residency's continued popularity since it launched in July 2025 and has already been extended several times.

Tickets go on sale in stages: a fan club presale opens on Tuesday 18 August at 10am PT, followed by an artist presale on Wednesday 19 August, before general sale via Ticketmaster begins on Friday 21 August. VIP packages will also be available through Vibee, while resale platform Vivid Seats is offering deals for fans. The band has further Sphere dates through 29 August before heading to Düsseldorf, Germany, for another residency; the "Into the Millennium" show celebrates their 1999 album with a mix of career-spanning hits, choreography and Sphere's signature visuals.
