According to In Touch, Jennifer Lopez and Ryan Seacrest are both battling to become the top diva of American Idol.

An insider said:

“Ryan was the one who first suggested Jennifer, but now he’s starting to regret it, because she’s acting like she’s a much bigger star than he is. Ryan knows the diva behavior is likely to get worse before it gets better. Producers are trying to get them to make peace, but their egos are both pretty big.”

The two have been battling over everything from their dressing rooms to receiving top billing.
