Backstreet "Boy" No Longer — Nick Carter is Married!

Our teenage selves are crushed: The youngest member of "The Boys" is now a married man!

Nick Carter and his fiancée Lauren Kitt, a fitness expert and actress, tied the knot at the Bacara Resort and Spa in Santa Barbara on April 12. Fellow Backstreet members AJ McLean, Howie Dorough and Brian Littrell were among the 100 guests who celebrated the 34-year-old singer's big day. In fact, McLean's daughter, Ava, served as the flower girl!

The bride stunned in a sexy, strapless mermaid gown with lace accents and upswept locks. Not to be outmatched, the dapper groom donned a custom black Anthony Franco Designs tux with a matching bow tie.

The newlyweds recited their vows underneath a white and purple chuppah overlooking the ocean at sunset. A source tells Us Weekly that the bride was so moved that she reached out and put her hand on her groom's chest: "At the end of the ceremony, they shared the longest wedding kiss I've ever seen. 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 '90s heartthrob proposed to his now-wife in February 2013 on what he referred to as "Engagement Island," an undisclosed location in the Florida Keys. He presented her with a seven-carat, pear-shaped diamond ring from XIV KARATS. According to People, Carter went to Dorough for advice before popping the question: " I was like, 'I love her, and I don't want to lose her.' And he was like, 'Just do it!'"

Congratulations to the happy couple!
