Another Backstreet boy or girl is on the way! Multiple sources have confirmed that Backstreet Boy singer Nick Carter and wife Lauren Kitt are expecting their first child together.

According to Us Weekly, Kitt, a fitness trainer and actress, is four months pregnant. Carter, who is currently competing on ABC's "Dancing with the Stars," has yet to confirm the news.

"They are so happy and overjoyed," a source told Us Weekly. "They've been trying and waiting for such a long time."

Carter and Kitt, who met on a blind date in 2008, tied the knot at the Bacara Resort in Santa Barbara, Calif., in April 2014. According to Us Weekly, the 36-year-old pop star proposed to his ladylove — with a 7-carat, pear-shaped diamond ring — during a romantic vacation in the Florida Keys.

"They shared the longest wedding kiss I've ever seen," a source told Us Weekly at the time. "A full minute later they were still kissing. They seem crazy in love and thrilled to be married. You could feel the love bursting out of them."

The couple's relationship and road to the altar was filmed for the VH1 reality show "I Heart Nick Carter."

"I just felt an instant connection. It's like I just wanted to be around her," he told Yahoo in September. Kitt said, "You have to find someone that you love and that loves you just as much. We can spend 24/7 with one another. I can't even spend that with my sister or my girlfriends, but I can spend 24/7 with him."
