Last November, former Wonder Girls member Sunmi shared her love for the hit American show American Idol. Well, it seems as if Sunmi wasn't the only member in the Wonder Girls that watched American Idol! Not too long ago, Yeeun voiced her support for a current American Idol contestant. She tweeted, "OMG who else just watched Crystal singing on AI?! I gotta say she just rocked !!!! Amazing perform!!" This Crystal that she mentions is none other than Crystal Bowersox from Elliston, Ohio. Currently, Crystal is among the top 11 contestants of the ninth season. With her amazing voice, it's no wonder she made it this far! Check out her latest performance and tell us what you think! Do you agree with Yeeun? http://www.youtube.com/watch?v=dRIKvr4sYSA
