'American Idol' 2010 finale: Simon Cowell's last red carpet walk


It was a red carpet moment for the "American Idol" history books.

Judge Kara DioGuardi sparkled in a silver one-shouldered gown on the "Idol" Season 9 finale carpet, posing pretty for the cameras. Then she turned to Euro-kiss her fellow judge Simon Cowell and his fiance, Meghen Hussainy, wearing a strapless short metallic number.
