Simon Cowell’s eyes almost popped out of his head when Katrina Darrell showed up for this years American Idol auditions.

The slim beauty was scantily clad in a revealing bikini and I reckon even if she hadn’t sang at all Simon would have put her through to the Hollywood stage.

After Katrina finished her Mariah Carey song Simon blurted “Yes.”

Asked: “No more explanation?” he replied: “No. She’s just in.”

New judge Kara DioGuardi recommended: “Next time come naked.”
