Backstreet Boys on Nick Carter's Wedding: 'It Was Bittersweet'

"Next step is having kids," A.J. McLean said.

April 14, 2014 — -- Backstreet's back alright!

On Saturday, Nick Carter married Lauren Kitt in Santa Barbara, Calif. and of course his fellow band members were there to help celebrate his special day.

"It was bittersweet," A.J. McLean told People magazine. "We're so, so proud of him. He's been through hell and back as we all have, once in our life here or there."

The Backstreet Boys were a dynamic boy band until the early to mid-2000's, when they took a hiatus. In 2009, Carter admitted to past drug use and alcohol addiction.

McLean added that Saturday's wedding was "beautiful" and "rustic."

"We're all brothers," he told People. "To see our little baby brother finally make that big, big final step. Next step is having kids. Obviously they just got married, so obviously take your time."

"Enjoy your time together first," Brian Littrell added.

The couple were married at sunset on a bluff overlooking the ocean at the Bacara Resort in Santa Barbara.

Carter, McLean, Littrell, Howie Dorough and Kevin Richardson were the founding members of the Backstreet Boys.
