Backstreet Boys

Backstreet Boys have added even more shows to their residency at the Sphere this summer.

Backstreet Boys announced a series at Sphere; the band has a history in Las Vegas.

The event was remarkable as a Luxor/MGM Resorts act supported a Planet Hollywood/Caesars Entertainment headlining residency.

The front man for Aerosmith joined the Backstreet Boys onstage at Zappos Theater on Friday night.
