Remember Bikini Girl? The infamous contestant who kissed show host Ryan Seacrest and had a quarrel with Kara DioGuardi during her American Idol auditions? Well, her stunt paid off and she got a spot on season 8’s finale! Unfortunately for Katrina “Bikini Girl” Darrell, the show’s producers played a lil prank on her. While she performed Mariah Carey’s “Vision of Love”, her nemesis judge Kara DioGuardi surprised her onstage and sang along with her. Kara even bared her bikini body at the end of their performance! Bikini Girl shared,

“I don’t think she got the reaction she was hoping for. I think she probably thought I would cry or get mad, and I didn’t — I played it off. Looking back at the tape, she just made herself look stupid; she didn’t make me look stupid.”

Katrina Darrell added, “I knew there were 100 million viewers, so I couldn’t cry. I couldn’t get mad. I just had to smile and deal with it. The show producers kind of said, ‘I’m sorry.’ I think they tested me. I think I did really well, considering all that I went through.” After Kara DioGuardi stole her performance, Bikini Girl alleged her little sister had a nasty run-in with the American Idol judge backstage. Katrina recounted, “We were walking, and [Kara] said, ‘Oh, sweetie, I hope you didn’t take anything personally.. I rolled my eyes, and my sister said, ‘Hey, next time you try to upstage my sister, get a spray tan! How old are you — 45 or 50?’ I looked back and shrugged. She kind of said what I was thinking but couldn’t say!”
