Jennifer Lopez Jennifer Lopez

Jennifer Lopez may be saying farewell to American Idol.

The singer-actress-reality show judge seemed iffy about returning to the Fox singing competition while appearing on Ellen Tuesday. "I don't know," Lopez said. "I really do enjoy it. 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." She noted that now that her kids are growing up, it's harder to give up her time.

However, sources told E! Online that Lopez is definitely planning not to return to the series because she's too busy with her upcoming concert tour alongside Enrique Iglesias.

The news comes a few days after Fox recruited Britney Spears to judge The X Factor for a reported $15 million contract. Could the timing mean Lopez is holding out for a bigger payday?
