On Monday's episode of Gossip Girl, "There Might Be Blood," Jenny decided to go for broke and launch a "guerilla" fashion show for her line, called J Humphrey Designs.

As Jenny's cohorts hijacked a projector and played a loud, edgy music video, a team of models dressed in her trendy designs pranced around a fancy NYC charity gala.

Now, the CW has posted the very music video it created (and played) to promote J Humphrey Designs on the show - featuring shots of Jenny, Agnes and friends.

The song is "Calypso" by Blonde Acid Cult. Check out the video below ...
