Backstreet Boys' A.J. McLean tied the knot with bride Rochelle DeAnna Karidis in a goth-themed wedding at the Beverly Hills Hotel in California.
The two were wed under a gazebo covered with white hydrangeas, while guests were surrounded by chandeliers.
Friends said McLean, who wore a red bow tie, "looked happy and excited" before the ceremony.
The small ceremony was followed by dinner and dancing in the Crystal ballroom.
On Friday, McLean tweeted "Wedding is tomorrow. Ro and I could barely sleep last night. I think we're a little excited."
