Congratulations to LeAnn Rimes and actor Eddie Cibrian, who said "I do" Friday, April 22, in a private surprise ceremony held in California.

Those in attendance were made to believe they were invited to an engagement party, but the couple surprised them all by tying the knot at the intimate gathering of roughly 40 guests.

"LeAnn and Eddie were happily married today surrounded by their closest family and friends," the singer's publicist, Rhett Usry, confirmed to PEOPLE. "They thank everyone for their well wishes."

The beautiful bride, 28, wore a Reem Acra gown as she and Cibrian, 37, exchanged personalized vows on Friday in front of their guests, which included the actor's two sons, Mason (7) and Jake (4) from his previous marriage.

The couple have been engaged since December when Cibrian popped the question to Rimes with a 5-carat diamond ring. This is the second marriage for both of them.
