Nick Carter is off the market!

The Backstreet Boy, 33, married fitness expert and actress Lauren Kitt, 29, in a breathtaking ceremony in Santa Barbara, Calif., on April 12, his rep Jack Ketsoyan of EMC Bowery tells In Touch exclusively.

"This is the best day of my life," Nick tells In Touch. "I'm so happy to be marrying the love of my life."

The pair got engaged last February when Nick popped the question -- with a seven-carat diamond ring! -- during a romantic boat ride to a secluded island in the Florida keys.

Congrats to the happy couple!
