'Kpop Star 3' Nam Young Joo flaunts once again the fruit of her labor through a sexy concept poster.

Earlier today, the singer released a gray-scale poster showing a silhouette of her curvy body behind a shower curtain while holding a mic. A representative describes the photo as a reflection of Nam Young Joo's debut concept which is 'sexy without too much exposure'.

In comparison to her image from 'Kpop Star 3', the singer looks more confident and sexier after losing 11kg in one month as a part of her debut. Meanwhile, Nam Young Joo released her debut single "6:09" on September 16.
