Calm down — no reunion date is set for Utah yet. But maybe ...

NKOTB and BSB (if you don't recognize the acronyms, you probably aren't all that interested in the groups) shocked and delighted fans when they took the stage together for a medley at the sold out NKOTB Radio City Music Hall show (above).

The collaboration ignited rumors that swirled for months. And now, as announced exclusively on Ryan Seacrest's radio show, New Kids on the Block and Backstreet Boys are making it official.

NKOTBSB will begin in the summer of 2011. Tickets to this "historic" event go on sale beginning November 19th at Ticketmaster.com and Live Nation.com. The NKOTBSB tour, produced by Live Nation includes confirmed dates in Toronto, New York, New Jersey, Chicago and Los Angeles with additional dates to be announced soon. The public will get their first sneak peak of what's to come on November 21 as all nine men perform LIVE at the American Music Awards in their first joint televised appearance.
