Backstreet's back, alright.
For the first time in six years, Nick Carter, Brian Littrell, Howie Dorough, A.J. McLean and Kevin Richardson reunited as the five Backstreet Boys performed live on Good Morning America's Summer Concert series in New York's Central Park.
The quintet sang "Incomplete," "I Want It That Way" and "Everybody (Backstreet's Back)." Check out their GMA reunion concert below and see what you think:
Afterward, the show's news anchor, Josh Elliott, referring to absent co-host Robin Roberts - who on Thursday both departed the show to begin medical treatments and lost her mother, 88-year-old Lucimarian - said, "Robin, that one was for you."
Be well, Robin, and stay strong.
