Justin Guarini, runner-up to Kelly Clarkson in the first season of American Idol, is getting hitched.

The singer, 30, is set to wed fiancee Reina Capodici Saturday on a private estate along the Delaware River near both their families' homes in Pennsylvania, has learned.

Instead of  traditional wedding music, special arrangements by the Vitamin String Quartet, featuring artists like Radiohead, Paramore and Peter Gabriel, will be performed.

A female minister from the Universal Church will preside over the ceremony.

The couple also have written their own vows for the "spiritual" service.

The two have know each other since high school, but only started dating a few years ago.

They decided to get married in last December when Guarini was in Florida at Disney's EPCOT Center filming his "hosting clips" for the "American Idol Experience" ride.

Capodici, 27, has a 4-year old daughter, Lola, from a previous relationship.
