Oooooooooh!! This is SO exciting!
The Backstreet Boys are going on tour AGAIN this summer!!!
Those five guys, Nick Carter, Brian Littrell, A.J. McLean, Kevin Richardson, & Howie Dorough, paid a visit to Good Morning America to spill the AH-MAZE news!
Plus, they're being joined by Avril Lavigne!
Sounds like so much fun!
Let's just hope she doesn't storm off stage again!
