Sorry, girls. This former Idol is officially off the market. American Idol Season One runner-up Justin Guarini will marry fiancee Reina Capodici, 27, in an intimate ceremony in Pennsylvania this Saturday.

The intimate family wedding will be held on a private estate along the Delaware River, not far from both their families’ homes in Pennsylvania.

The lovebirds have written their own vows for the “spiritual” service, to be officiated by a female minister at the couple’s church.

The couple have known each other since high school but only started dating a few years ago. They announced their engagement last December.

Justin will also become stepdad to Reina’s 4-year-old daughter Lola.

Guarini, 30 recently worked as a correspondent on the TV Guide Channel’s Emmy Awards coverage and he hosts Idol Tonight for the network. He plans to head back to the studio to work on another album this winter.
