The last of the Backstreet Boys is off the market. Nick Carter, 30, said "I do" to his fitness model girlfriend Lauren Kitt on April 12 in Santa Barbara, California. The pair exchanged vows under an arbor filled with purple and white blooms. The bride wore a strapless, mermaid-style gown with lace appliques to walk down the aisle, while the groom had on a fitted black Anthony Franco tux. The "I'll Be the One" singer's BSB band mates, Howie Dorough and A.J. McLean joined the duo for their special day.
