Female Idols in a Bunch over Barba

Sources have revealed to TMZ that there's a feud a brewin' backstage at "American Idol."

According to our spy, some of the religious female contestants are none too fond of one Miss Antonella Barba, since racy photos of the off-key idol began popping up on the net.

No confrontation has erupted, but it's been downright chilly behind the scenes, with the idolettes now waiting to see if America decides to keep the photogenic Barba around for another week, heaven forbid!

When contacted, reps for "Idol" had no comment.
