The singer-actress had been closing a deal to be a permanent judge on the show for its upcoming 10th season but the deal fell apart.
"Her demands got out of hand,” says the source. "Fox had just had enough.”
With Simon Cowell and Ellen DeGeneres both departing the talent search, the network had been pursuing a number of celebrities as potential judges, including Aerosmith's Steven Tyler.
But now that Lopez is out of the running, the network may be looking at their earlier top picks again.
Other reports have said that the panel could go back to the original three-judge format.
Fox had no comment. A rep for Lopez did not immediately return calls for comment.
