The CW has dropped a new promo from the next episode of "iZombie," "Fifty Shades of Grey Matter."

The promo introduces us to a steamier Liv than we're used to, after she's eaten the brain of an erotica writer.

Created for Vertigo by Chris Roberson and Mike Allred, and adapted for television by Rob Thomas, "iZombie" airs Tuesdays at 9/8c on The CW.
