Girl group Rainbow's Go Woori pretended to be a gangster member with After School's Lizzy.

Yesterday, Go Woori posted on her Twitter, "Scary girls at 'Inkigayo'" along with a picture.

In the picture, Lizzy and Go Woori are pretending to beat up Rainbow's Jisook. Jisook looks scared.

Internet users who saw this commented, "Go Worri and Lizzy must be close," "Jisook's face looks so real," "Lizzy looks like an actual gang member," and "Are you sure this is pretending?"
