By now everyone knows who the Karmin duo is. Also, it is pretty obvious how hot the singer of the group is with her beautiful eyes and great smile. Besides all that though, they have really made a name for themselves doing covers for many great artists such as Nicki Minaj and Chris Brown among many others. This one is for a Rocawear ad where they cover Jay-Z’s “Carbon Copy/Encore” and it is so far my favorite one of them all. Enjoy!
