London, Jan 17 : Hopeful Katrina Darrell left American idol judge Simon Cowell in complete awe when she turned up in a bikini at the show's auditions.

While the judges decided whether to put her through auditions Cowell immediately said: "Yes."

When asked: "No more explanation?" he replied: "No. She's just in."

The part time model murdered a Mariah Carey song on the ITV2 talent show, reports the Sun.

While fellow judge Randy Jackson said: "You have potential", new judge Kara DioGuardi bitched saying "Next time come naked." (ANI)
