Appearing on the Today show Thursday morning, Jennifer Lopez implied that she's considering quitting as a judge on American Idol and taking her career in another direction. This news arrives one day after it was suggested that J.Lo's fellow judge Randy Jackson might also be leaving his place behind the table and could be replaced by former Idol runner-up Adam Lambert.

When Lopez was asked by Today correspondent Natalie Morales about her future with the hit show, she didn't sound confident she'd be returning.

It's been on my mind a lot, as you can imagine, Lopez said. I signed on to 'American Idol' to do one year and I wound up doing two years. And now it's like 'OK, do we continue on this journey?' I've loved it so much ... so it's a tough decision either way. But I have to say that there are so many other things that I do, and that I put on hold for that. At the end of the day, whichever way, it's going to be a heartbreaking decision.

Lopez refused to give a flat yes or no answer, although her comments certainly suggest she'll no longer be appearing on the show. This announcement comes two seasons after she and Aerosmith lead singer Steven Tyler rejuvenated the show by replacing Simon Cowell and Paula Abdul. Fans immediately welcomed the fresh energy of the new judges.

Lopez posted the video of her interview on her own website, which you can find here.  

E! Online has also reported that Fox has been considering Adam Lambert as a replacement for longtime judge Randy Jackson. Jackson's contract is up, and even though Lambert has been spending time as the front man for revived rock group Queen, he has said he'd be willing to make time for the show that he credits with starting his career. But Lambert denied being contacted by the show to replace Jackson.

E! Online quoted a source as saying, Randy is great but he's part of the old 'Idol.'

Steve Tyler's future is also up in the air with the show, report multiple sources. After Tyler signed onto Idol, Aerosmith bandmate Joe Perry took to the press to criticize his lead singer, but the band has since patched up their conflict and are touring the country promoting their new album, which is due in November.

Earlier this week E! Online speculated that the list of potential replacements for the current judges includes names such as Miley Cyrus, Nicki Minaj, Will.i.am, Katy Perry and Fergie.  Auditions for season 12 are in progress.
