Say "bye bye" to the sexy black outfits from yesterday's sexy performance of Jewelry's One More Time, folks, because Rainbow is back on today's Music Core stage with their debut single Gossip Girl. As much as I love all the bright colors and all that good stuff that comes along with their generic Gossip Girl performance, I would much rather have these girls revert back to that sexy image they portrayed with Jewelry's cover performance. Come on, you know you agree. Perhaps by taking on a more appropriate sexy image, these girls can reach the initial acclaim of being the 2nd Fin.K.L. Until that day comes along however, we'll just have to settle for what we're given. Check out their performance below!
