Bikini girl (Katrina Darrell) reappeared one more time on Idol last night before falling back into the ether never to be heard from again. What she performed wasn’t that important because she was strutting around in a bikini the whole time, but then Idol judge, Kara Dioguardi, walked on stage and started singing and took the focus off Katrina. Boooring. At least she spiced things up by flashing her own bikini towards the end. For about three seconds. Luckily, shutter speeds are fast enough so what seems like three seconds can turn into two minutes, maybe even three with the right technique.
