"iZombie" is going to set a "Veronica Mars" reunion. Kristen Bell will be featured in an upcoming episode of The CW's series from "Mars" creator Rob Thomas, but there's a twist. Instead of appearing on the show, she will have a voiceover role.

Bell, who is currently a series regular on Showtime's "House of Lies", will lend her voice to episode 11 titled "Fifty Shades of Grey Matter" which is slated to air on January 26. According to EW, in the episode "things get interesting for Liv (Rose McIver) after she consumes the brain of a young librarian who was poisoned, and who also happened to secretly be an erotic fiction writer."

Details of how Bell fits into the storyline are still kept under wraps. She's the latest "Mars" alum who guest stars on the comic book adaptation following fellow former co-stars Ryan Hansen, Percy Daggs III, David Starzyk, Adam Rose and Daran Norris.
