American Idol contestants should not attempt Jennifer Lopez tunes

Note to contestants hoping to impress American Idol judge Jennifer Lopez: Don’t sing her songs.

“It was cute, super entertaining and flattering, but no,” the pop diva says of contestants who failed to make it through auditions by performing one of her hits.

“They know we’re not out to cut them down or make a joke of them,” she told reporters Thursday at a stop in Los Angeles. “We’re trying to mentor them to the next step.”
