Singer Baek Ah Yeon supported Park Ji Min's debut.

Yesterday, Baek Ah Yeon posted on her Twitter, "Cute Ji Min that came to MV filming for 'Slow Song'! Our Ji Min is debuting soon too!!^^~ You'll do well fighting!!!" along with a picture.

In the picture, Baek Ah Yeon and Park Ji Min are hugging each other, making cute faces at the camera. Baek Ah Yeon wore a blue tube top dress that made her look much more mature, and Park Ji Min kept the fresh teenager image.

Park Ji Min will be making her debut this coming October with a girl the same age as her in the group '15&'.
