The star, who played Michael C. Hall's onscreen wife on the serial killer series, will move into Wisteria Lane as Debbie, a stripper who is taken under the wing of Teri Hatcher's character Susan Delfino as she strives to leave the adult entertainment industry.
According to EW.com, Benz's role will initially appear in three episodes.
Benz was written out of Dexter at the end of season four last month (Dec09) when her character Rita was found lying bloody and lifeless in the bathtub.
