There was a point last season when Jennifer Lopez didn't know whether she would return to American Idol.

"I got a little bit tired at the end with everything going on in my life at the time," says Lopez, whose split with husband Marc Anthony was announced less than two months after the finale.

But at a news conference in Savannah, Ga., where the show is taping, Lopez told reporters that she realized Idol was "one of the best things I've ever been involved with" and that she enjoyed working with the contestants as well as fellow judges Randy Jackson and Steven Tyler and host Ryan Seacrest.

"I was like, 'Okay, I'm gonna do it again,'" she says.

Earlier this month, producer Nigel Lythgoe had made it official, announcing that Lopez was coming back for a second season.
