Brown Eyed Girls' Narsha pushed the limits once again as an 'adult idol' by showing some major cleavage (for K-pop standards that is) for 'Arena's March issue.

Narsha, who just turned 31 years old (international age), proved that age is just a number and embraced her maturing image with her wind blown hair and white lace bustier.

But don't be fooled because Narsha is not only sexy but talented, a complete package. She lamented that she feels as if she's only just started to receive recognition for her voice, and commented, "Although it's been seven years since my debut, I recently heard 'so Narhsa does sing well' after performing on 'Immortal Song 2'."

The Brown Eyed Girls are known for embracing their 19+ image as they have specifically catered to their more mature audience with a special concert, and who could forget Ga In's music video for "Bloom"? This has us wondering, which Brown Eyed Girls member will be next to push the limit?
