A source close to Lopez -- whose name was not revealed -- told People reports that the star asked for a $2 million raise to continue judging the Fox show are untrue.
Fox approached Lopez with a "comparable offer to last year's salary" for her third season, but Lopez never gave a counter offer, the source said.
Lopez earned $15 million for her first season judging the show and was given a raise to $20 million for her second season after Fox saw the value she brought to the show, People said.
Ultimately Lopez, 42, said she decided to leave the show to focus on her family, film and music careers and her fashion business.
"I could do Idol for the rest of my life," Lopez said of her departure, "but that would be giving up a bunch of other things ... I have my movies and my music and my this and my that. It all kind of worked together for a while, but then it gets more complicated."
