Nick Carter has officially found his one desire.
"This is the best day of my life," Carter, 33, tells In Touch. "I'm so happy to be marrying the love of my life."
Among the guests at the festivities were Carter's former bandmates A.J. McLean and Howie Dorough. McLean posted a selfie on Instagram before the rehearsal dinner on Friday night, with the caption, "Chillin at the house getting ready to head to the rehearsal dinner of the wedding most of u thought would never happen but I'm so happy it is finally! Congrats to my little bro for growing up and finding love. So proud of u bro. Love u both @nickcarter and @laurenkitt."
