She may play a preppy schoolgirl on "Gossip Girl," but Taylor Momsen sets out to shock in her new music video.

The actress turned frontwoman for the band The Pretty Reckless oozes blood in the dark video for the group's song "Just Tonight."

Momsen expresses teenage angst singing, "Do you understand who I am? Do you want to know? Can you really see through me now?"

This isn't the first time Momsen has shocked people with her outlandish behavior. The 17-year-old has been known to show up for shows wearing scantily clad clothing.
