Here’s hoping someone told Twilight Saga star Christian Serratos that the zombies on AMC’s hit series “The Walking Dead” don’t sparkle. Serratos is joining the show’s fourth season as stunning zombie apocalypse survivor Rosita Espinosa.

Rosita Espinosa was introduced in issue 53 of the Robert Kirkman comic book series. Serratos will recur as the character in the upcoming fourth season with the option to return as a series regular in season five.  “The Walking Dead” returns on Oct. 13.

In addition to Serratos’ casting, AMC has announced that it will produce a “Walking Dead” spinoff series focusing on “an entirely new story and cast of characters.” The series is slated to debut in 2015 with Kirkman on board as an executive producer.
