Tell me why … Backstreet Boys keep on tacking on more dates to their Las Vegas residency? Apparently, it’s due to “continued fan demand.”
The group’s added what they say are the “final run” of summer dates for their Into the Millennium show at Sphere Las Vegas. The new shows are set for Aug. 27, 28 and 29. The group’s summer run of shows at the venue begins July 16 and was initially set to wrap up Aug. 22.
