Jennifer Lopez's North of the Border Music-Making Magic

And it sounds like J. Lo will have plenty of free time coming up this fall, as she’s announced she won’t be returning to “American Idol” in the new season.

Lopez explained that Steven Tyler’s departure made her decision final- "We had magic. I don't know, with him gone, it might be a different formula."

As for who should replace Tyler, Jennifer suggested, "I think like Bono or Bon Jovi or Mick Jagger. You know me, I think big."
