Get ready to scream for your favorite boy bands, because the heartthrobs of New Kids on the Block and Backstreet Boys are taking their shows back on the road!

The North American concert tour kicks off in the summer of 2011, but all nine guys will be interviewed On-Air with Ryan Seacrest on Nov. 8.

ET was exclusively with the groups during a rehearsal in June when the Backstreet Boys surprised NKOTB fans at Radio City Music Hall in New York City by performing "I Want it That Way."

"I think this is definitely a special collaboration and timing is everything in show business," New Kid Joey McIntyre told ET of the collaboration. Backstreet Boy Howie Dorough added, "We've always said they've inspired us to be the group that we are."

 But you don't have to wait till next summer to see the boy bands! The guys will be performing live together on Nov. 21 at the American Music Awards airing on ABC.
