Jennifer Lopez just announced ... she will NOT be returning to "American Idol" next season.

JLo called in to Ryan Seacrest this morning, saying, "I honestly feel like the time has come that I have to get back to doing the other things that I do."

She added, "We had an amazing run."

Lopez made the announcement a day after Steven Tyler bailed from the show. And there is a strong buzz that Randy Jackson may not be coming back either, leaving Ryan Seacrest the last man standing on the show, which has lost a third of its ratings in the last year.

Obviously, producers now have to make a decision that will make or break the show.
