The boys of 2PM were back again to perform on today's episode of Music Bank as they are coming back from a triple crown celebration just yesterday on Mnet's M! Countdown. If you guys remember, the boys also won last week's K-Chart so there is a chance for the boys to win two consecutive K-Charts. The boys performed their latest hit track Without U, check out their fierce and beastly performance below! http://www.youtube.com/watch?v=Yz3dKQ6FhvI http://www.youtube.com/watch?v=oAUKRyZo7ks The boys hit success yet again as they won today's K-Chart against Kim C to make it two consecutive wins in a row! Congratulations to the boys once again. http://www.youtube.com/watch?v=c1TVLcfBIf4 Now for Mutizen on Inkigayo this Sunday, the only award that they have yet to receive.
