The American Idol-bred celeb tied the knot Saturday with longtime girlfriend Reina Capodici at a private estate on the Delaware River, not far from the couple's Pennsylvania home.

Guarini, 30, and Capodici read their own vows during the ceremony, which was presided over by a female minister from the Universal Church.

The newlyweds actually met in high school—long before Guarini's curly mop top was making tweens scream on the premiere season of Idol—but they didn't start dating until three years ago. They decided to get married in December.

Capodici has a 4-year-old daughter, Lola, from a previous relationship.
