American Idol’s fourth judge Kara DioGuardi sang a duet with American Idol ‘Best Attitude’ winner Katrina Darrell on the night that Adam Lambert got robbed.

Katrina began Mariah Carey‘s “Vision of Love,” much to the dismay of the crowd that quietly booed, then Kara jumped in and proved that she can sing. I wouldn’t say sang, but she can sing.

During Katrina’s time away from Idol she got herself what looks like some D-cup breast implants. No comment.

After Kara DioGuardi sang with the talentless Katrina, she then ripped open her coat and revealed her black bikini. As you can see, Kara has some great ribby abs! Heh. But she is not confident. Couldn’t Kara fake confidence, have fun with it and work it for like two seconds during the finale last night? Kara’s a pretty good singer, but an awkward performer. I thought DioGuardi was gonna urinate at the end of her performance. Did she have to be crossing her knees like that?! Well, I thought she was gonna urinate or fall down. I was hoping for both!
