The mystery Jellyfish Entertainment artist that will be dueting with singer Lyn turned out to be a member of VIXX.

The agency still has much to tease with, however, as it hasn′t revealed who the member will be.

On July 30, the agency dropped a hint in the form of a teaser image with captions reading, ′Lyn X Who? of VIXX′.

Fans showed their excitement for the collaboration by swarming to the site, resulting in their taking down Jellyfish Entertainment′s servers.
