BEAST/B2ST, who is currently promoting Bad Girl, will perform 2PM's Again and Again! Many fans are especially paying attention to this because BEAST & 2PM have a history together. We've reported in the past that the president of Cube Entertainment, Hong Seung Sung was originally a JYP Entertainment representative, and had a part in debuting 2PM. BEAST's leader Yoon Doo Joon actually auditioned for 2PM; three other members Lee Ki Kwang, Soon Dong Yoon and Yoseub were JYPE/CUBE trainees in the past. With all these ties, fans have been calling BEAST the brother group of 2PM. What's more interesting, at least for me, is that BEAST also claimed to be aiming for the title of "beastly idol." One of BEAST's members commented, "Our relationship with 2PM is like a brotherly kinship. We have decided to perform this song with our hearts & minds for 2PM and Jaebeom." Here is a sneak peek of what's to come @ 0:55: Cr: CodeMonmonSeason3 Stay tuned for BEAST's performance of Again and Again today on Mnet's M! Countdown!
