In fact, the newly-single Lopez didn't even know whether she would return to Idol next season until the very last minuet.

At a news conference in Savannah, Ga., where the show is taping, J. Lo confessed to reporters:

    "I got a little bit tired at the end with everything going on in my life at the time ... but Idol is one of the best things I've ever been involved with. I was like, 'Okay, I'm gonna do it again."

Lopez split with husband Marc Anthony less than two months after Idol's seaosn finale.

Season 11 auditions will take place in Denver, Houston, St. Louis, Portland, Ore., San Diego, Pittsburgh and Charleston, N.C., and are set to kick off in a couple weeks, according to Ryan Seacrest's Twitter page.
