They’re gonna be lining up at the boxoffice for this one.

from www.radaronline.com – Jon Gosselin’s ex-girlfriend Hailey Glassman will be starring in a horror flick with famed porn star Sasha Grey.

And — don’t get insecure Jon — but there’s a possible lesbian scene in the works too!

“Hailey was approached to read for a small role in the movie and did so well that they called her back for a larger role,” a source close to casting told RadarOnline.com exclusively.

“She got the part and will pretty much be the supporting actress to Sasha.”

The insider told RadarOnline.com that the horror film is tentatively named Hallow, and it’s a movie done by the same writers as 2002’s Cabin Fever.

“The movie will be shot in Vancouver, Canada, and they’re planning on starting production sometime next month,” the source said.

“There’s a possible lesbian scene in the works but she’s still in the middle of negotiations about doing it.”

Being on a movie set and making a feature film is not something Glassman is familiar with, but the insider said they’re sure she’ll catch on quickly.
