Singer Gain's naked face from the past is catching attention again as she admitted her relationship with actor Joo Ji Hoon.

In May 2011, member JeA had posted on her Twitter, "Rest in downtown. Gain and me endlessly eating. The endless room service. I feel so good" along with a self-camera photo.

In the picture, Gain and JeA took off their makeup completely. It caught more attention that Gain had a naked face as her thick eyeliner is her trademark.

Gain and Joo Ji Hoon's agencies admitted yesterday that they are in a relationship. The two have been friends for 8 years and recently developed into a couple. The two had also filmed a rated-R music video for Gain's song.
