Actress and MC Kim Jung Eun has recently celebrated the 2nd year anniversary for her program Kim Jung Eun's Chocolate. Earlier this week, news broke out of Kara's surprise appearance on the show, but in addition to their mini celebration with cake, the girl group went on to perform a medley of their hit singles like Pretty Girl, Honey, Mister and their current chart topper Lupin. The girls also offered a dance tutorial for their booty shaking track Mister and Nicole offered some great eye candy of her own when she performed Mister solo for the audience. And as if that weren't enough, a sexily dressed Kim Jung Eun shared the stage with 2PM's beastly rapper Taecyeon for a sexy rendition of Baek Ji Young's My Ear's Candy. At the very end, the two artists provide the audience with some laughs with their little Heartbeat spoof. Several other artists like Psy, Jung In, and Leessang made an appearance on the program to show their support.
