Backstreet's back, all right!
Brian Littrell, Nick Carter, Howie Dorough, A.J. McLean and yes, even Kevin Richardson, reunited for the first time in six years to perform a selection of their biggest hits during a Friday Good Morning America concert in New York City's Central Park.
Currently working on their fifth studio album, which they'll release with the help of original member Richardson, 40 -- who left his band mates Littrell, 37, Carter, 32, Dorough, 38, and McLean, 34 in 2006 -- BSB belted out "Larger Than Life," "Everybody (Backstreet's Back), "Incomplete" and "I Want It That Way" for a massive outdoor audience.
Following the group's opening number, "Incomplete," GMA anchor Josh Elliott offered a quick song dedication. "Robin, that one was for you," Elliott said, referring to beloved GMA mainstay Robin Roberts, whose mother, Lucimarian, passed away Thursday -- just days before Roberts is scheduled to undergo a bone marrow transplant using a donation from her sister Sally-Ann.
"We definitely have some of the best fans in the world, that's for sure," Carter told anchor Lara Spencer. "It's like we never stopped -- and now we've got Kev back, so now Backstreet's back," added McLean.
Also on Friday, the group confirmed an October 2013 Backstreet Boys cruise to coincide with their 20th anniversary. "2013's going to be a big year for us!" Richardson predicted.
