Bikini Girl Katrina Darrell [photos] returned to 'American Idol' last night to accept her award for Best Attitude but she wasn't the only one willing to show off a little skin.
In what proved to be one of the most surprising moments of the finale, fans were given a glimpse of Kara DioGuardi's bikini body as the 'Idol' judge made her show singing debut and revealed a tiny black bikini all in one go.
"What a stomach," host Ryan Seacrest told Kara DioGuardi. "We bet Kara she wouldn't do that and she did it. So, we're going to donate a lot of money to her favorite charity."
