Ga-in declares war on 2AM's Seulong?

Has Brown Eyed Girls' Ga-in declared war on 2AM's Seulong? Was it because she was jealous of his moobs (man boobs)? Nope, read on... It all started when Ga-in released a ssaeng ul (no-makeup face) picture to the public. 2AM's Seulong then posted a message on her mini homepage. "Oh my god ?? Why are you always showing your face with no makeup? ??" To which Ga-in responded "I am stretching in preparation to give you a back drop. You're dead! heehee!" This playful back and forth banter has gotten the attention of netizens. Some examples of the comments left by netizens: "What are you two doing?" and "Stop it you two, Jo Kwon will be mad!" Hopefully this beef won't go out of control like 2Pac and Biggie.
