Big Bang's Taeyang recently posted a picture on his Twitter, and it's been driving his fans wild. On April 15th, the sexy crooner posted the picture above and wrote, "Hi everybody :) how ya doin..?". �Taeyang can be seen posing against a wall, wearing a white tank, and puckering his lips ever so slightly. What do you think of the raw and casual picture? Source: @REALtaeyang
