Former American Idol finalist Josh Gracin now has enough children to field a family quartet.

Anne Marie Stevens, the 28-year-old U.S. Marine-turned-country singer's wife of seven years, gave birth to Isabella Sophia on Wednesday afternoon in Nashville, TN, Gracin's representative told Us magazine yesterday.

Isabella will join Gracin and Stevens' three other children: 6-year-old daughter Briana, 2-year-old son Landon and 1-year-old daughter Gabriella.

"We're all excited about the new addition to the Gracin clan," Gracin told earlier this year, according to Us. "And Briana, Landon, and Gabriella can't wait to meet their new brother or sister."

Gracin finished fourth on American Idol's second season in Spring 2003.  His self-titled debut album was released in June 2004 and debuted at No. 11 on Billboard's The Billboard 200 album sales chart, moving 57,048 copies in its first week of release.  It was later certified gold. 

"We Weren't Crazy," Gracin's second album, was released in April and has since sold approximately 68,000 copies.
