'American Idol' judge Kara DioGuardi has said that worries about the show often wake her up at night.
Speaking to The Los Angeles Times, DioGuardi said: "It wakes me up at night. Can you imagine?"
"Last night I woke up in the middle of the night and I thought: 'I've got to look at those performances."
"Did I clock that one wrong? Why didn't I say that? I could have been more supportive'," she said.
