Television actress Kirsten Prout will star as vampire Lucy in Eclipse/i>, the highly anticipated third instalment of the Twilight series, said her representative.
Imdb.com reports that Lucy is a prominent part of Jasper's backstory and builds a bloodsucking army with Catalina Sandino Moreno's Maria who along with the newest Cullen will eventually kill her.
The 19-year-old Prout, who started as Jennifer Garner's protege in Elektra but is best known for her role as girl-next-door Amanda on ABC Family's Kyle XY, will join stars like Robert Pattinson, Kristen Stewart and Taylor Lautner in the movie.
