On KBS 2TV Music Bank, girl groups KARA, Brown Eyed Girls, 4minute and After School will share the stage for a special joint performance. The four teams will come together to form "Girl's 4" and perform their own hit songs (which I presume will be Mister, Abracadabra, Muzik and Because of You respectively). Many fans are looking forward to the imminent collaboration of some of the hottest girl groups who dominated K-pop this year. In addition, each team's resident mascot - Seung Yeon, Ga In, HyunA and UEE - will unite as the project group 4Tomorrow to perform their digital single Tomorrow for the first time. Aside from the girl group galore on the coming episode of Music Bank, there will also be special joint performances from BEAST-MBLAQ, SNSD-SHINee-f(x), and Lyn-Kim Tae Woo-Hwanhee, to name a few. The celebrity-packed show will air on the 25th, so don't forget to leave a generous amount of cookies and a warm glass of milk beforehand as a token of thanks to Santa for this early Christmas gift.
