"Twilight" star Christian Serratos is joining AMC's "The Walking Dead" in Season 4, according to Deadline.


The 22-year-old actress will play Rosita Espinosa, a seductive character who was introduced in issue 53 of Robert Kirkman's comic book series, which saw Rosita and her travelling companions, Eugene and Abraham, encounter Rick and his group at Hershel's Farm during their journey from Houston to Washington. Serratos is set to recur in Season 4 with an option to become a regular in Season 5. No word yet on whether the characters of Eugene and Abraham will also be introduced next season.


Joining the show as a regular in Season 4 is "The Wire's" Larry Gilliard Jr., who has been tapped to play Bob Stookey, "a former Army medic who is deeply haunted by his past -- both before and after the apocalypse." Returning stars who have been promoted to series regulars include Chad Coleman (a fellow "Wire" veteran), Sonequa Martin-Green And Emily Kinney.


"The Walking Dead" Season 4 premieres Sun., Oct. 13 at 9 p.m. ET on AMC.
