I really do enjoy it, she told DeGeneres after the host asked about her future on the singing competition series. Now this is my second year -- I don't know if I can go for a third year. I miss doing other things. It really does lock you down, which was nice the first year with the babies being three, but now they're getting more mobile, they're about to go into school ... So I just don't know.

J. Lo inked a $12 million American Idol deal in 2010 for Season 10 of the show.

But Spears might beat J. Lo come next year, after signing a $15 million deal with Simon Cowell for to become a judge on the next season of X Factor.

On Access Hollywood on Monday night, Lopez offered Spears some advice for her upcoming judging gig.

I was like, 'Live TV! Eek.' It's a big thing to take on, but I think they're [Spears and Demi Lovato] both more than capable to handle it, Lopez said. Working with the singers and doing your thing and knowing what you're talking about from experience, and they both have that.

J. Lo also added that it is okay to root for the good guy and find the best in each contestant. Lopez has been criticized for coddling contestants on Idol.

You don't have to be tough, she said. There's not one way to do that, reality TV, and those competition shows [are] about being yourself. It's about being your best self, and I think that's the most important thing.
