Subscribe to Arirang World! http://www.youtube.com/subscription_c... Jewelry has been a force in K-Pop since 2001. The group's line-up changed over the years and in 2011, Jewelry was set with Baby-J, Eunjeong, Semi and Yewon. "Hot & Cold" is Jewelry's new digi-single. It's about how it feels to see an ex-boyfriend with a new woman.
