We didn't call this item "Backstreet's Back," because that would just be too damned obvious, but hey, if the shoe fits. Pop perennials Backstreet Boys are preparing their biggest tour of the, um, millennium, rocking 100+ arenas and stadiums worldwide on the 2019 DNA Tour, with 500k+ tix sold in the first 48 hours of the on-sale. Patriot Management's Ron Laffitte is brushing up on his choreography.

Single "Chances," penned by Ryan Tedder and Shawn Mendes, is the second foray from forthcoming full-length DNA (due 1/25), following Top 10 hit "Don't Go Breaking My Heart"; the new track was #1 most added at Hot AC radio, and its video earned 6m+ views in 72 hours. The lads performed the tune on The Voice on 11/13, and they'll appear on Ellen on 11/19; look for a splashy spot on a certain high-profile holiday TV special, as well, TBA. Twitter and Instagram went nuts and mondo press ensued.

The band's Larger Than Life Las Vegas residency runs through February.

Look, these boys turned to men some time ago, but their boyish charm clearly abides, and multiple generations of fans are still screaming. Which sounds real sweet to Laffitte and team.
