Jennifer Lopez has decided to leave American Idol after two successful seasons.

This morning, JLo revealed to Ryan Seacrest on KIIS-FM that she's going to focus on her music career and her two kids rather than renewing her contract on the hit Fox show.

There was speculation that Lopez was holding out for a bigger paycheck, however the superstar said it was never about the money ... and more about making a smart and responsible decision with the twins in mind.

Just yesterday, Steven Tyler announced he was leaving the show, as well.
