Clay Aiken isn't the only American Idol alum who's a dad-to-be.

Season four finalist Josh Gracin and his wife of seven years, Ann Marie, are expecting their fourth child together, the singer's rep tells OK!.

"We're all excited about the new addition to the Gracin clan," Josh says.

Their children, Briana, 6, Landon, 2, and Gabriella, 1, he adds, "can't wait to meet their new brother or sister."

No word on a due date for the couple.

A former Marine, Josh, 27, finished in fourth place on Idol and has since found success in country music. His 2004 self-titled debut album was certified gold and spawned three top 5 hits. His second album, We Weren't Crazy, was released in April.
