Ruben Studdard's publicist confirmed Wednesday the Season 2 "American Idol" winner has filed for divorce in Alabama from his wife Surata Zuri McCants.
The couple, who married in 2008, have no children.
TMZ said Studdard cited irreconcilable differences as the reason for the split.
"Ruben and Zuri have gone their separate ways," Studdard's representative told the celebrity news Web site.
