The script of the third instalment of the hit vampire series Twilight has reportedly been leaked on the Internet, sending fans into a frenzy. More than 100 pages of what appears to be the storyline from The Twilight Saga: Eclipse surfaced online Jan 5, reports contactmusic.com.

A screenshot, purporting to be of the opening page of the script, posted on The Dish Rag blog, shows Jackson Rathbone's name emblazoned across the paper, suggesting the script once belonged to the actor who plays vampire Jasper Hale in the franchise.

Bosses at Summit Entertainment, the production company behind the movies, were previously left red-faced when the manuscript of The Twilight Saga: New Moon was discovered by a hairdresser in St. Louis in May 2009.

The stylist won praise from Hollywood bosses after handing the script in and was invited to the film's US premiere.

The Twilight Saga: Eclipse is due for release in July 2010.
