Chris-Brown-T-ara1 The long-rumored Chris Brown collaboration with T-ara N4 has been exhausting to keep track of: Will it or won't it happen? It seems like now, thanks to a 15 second preview that's surfaced, it will! Hip hop producer Knotch released the clip online, and its quickly generating a lot of buzz. It's hard to judge a song based on only 15 seconds, but what do you guys think? Will it be the song of summer? (via PopDust)
