One of our favorite moments of the Idol Finale was when 'Bikini Girl' took the stage. She started singing Mariah Carey’s “Vision of Love” but had a huge surprise when Kara DioGuardi took the stage and started to duet with her.
We don't know if this was setup or if it was in fact a surprise but it was GREAT entertainment.
If you guys recall Kara and Katrina Darrell(Bikini Girl) went at it during the auditions. That's why it was great seeing them on stage together.
Watch the performance below:
