Girl group GLAM's member Zinni has been titled the "hottest B-girl" online.

Zinni's dance clip from SBS MTV show "Real Music Drama GLAM," has become the new online sensation.

In the video is the singer, who was a former B-girl, showing off the technical head spin moves, shocking the audience.

She even performs a dangerous stunt, falling in a 90 degree angle right off of the head spins. This type of wild action from such a sweet looking girl was definitely not expected by the fans.

Viewers could not hide their surprise, commenting, "How much dancing do you have to do to achieve those abs?", "That fall looks so dangerous!", and "She looks so sweet but her dancing is crazy fierce."
