(Cover) - EN Showbiz - Ashley Greene thinks the next Twilight script will come with a hidden tracking device.

The 23-year-old actress plays vampire Alice Cullen in the movie franchise, with the penultimate film in the series, Breaking Dawn - Part 1, due for release next year.

The movie is hotly anticipated, with fans across the globe desperate to find out what may happen, and Ashley says the producers have planned ahead to prevent any spoilers from being leaked on the Internet.

The star says she hasnt even read the script herself yet, and joked that when she eventually receives it, there will probably be a secret tracking device attached so the producers know what she does with it.

"I haven't seen the script yet. I reckon it will come in a sealed secret box, with a tracking device! No, although you have to be careful with them. Maybe they do hide tracking devices in there and we just don't know about it! she laughed.

The Twilight franchise also stars Kristen Stewart and heartthrob Robert Pattinson, who plays Alices older brother Edward.

In keeping with the books by Stephenie Meyer upon which the films are based, the next instalment will see human Bella Swan, played by Kristen, expecting a baby with Roberts vampire character Edward. (C) Cover Media
