Jennifer Lopez is reportedly out of the running to be part of American Idol‘s season 10 judges’ panel, a well-placed source tells People. With Simon Cowell and Ellen DeGeneres both having exited Fox’s ratings juggernaut, the network has been looking for suitable celebrity replacements. J. Lo had been widely rumored to be in the final stages of inking a deal, but it reportedly fell apart due to her demands. A Fox spokesperson declined to comment on the story.

In an interview with EW last week, newly returned exec producer Nigel Lythgoe stressed the importance of chemistry between the judges, as opposed to their individual star wattage. Stay tuned to for more Idol updates.
