(Cover) - EN Showbiz - Security on the set of Jennifer Aniston’s new movie has been increased because so many people are trying to get a glimpse of the star topless.

Jennifer plays a sex-crazed dentist in upcoming comedy Horrible Bosses. She spends most of the film trying to seduce one of her employees, even performing a series of sexy stripteases.

Jennifer has been filming several of the movie’s raunchiest scenes in the past few weeks, and the sight of her scantily-clad has sent passers-by into a frenzy. People are so determined to see Jennifer nude, they have even been climbing onto the roof of a nearby building, forcing movie bosses to hire more security staff.

“Jen’s character is supposed to be a nympho. She starts doing a striptease for Charlie Day’s character through a window, unbuttoning her shirt, that kind of thing,” a source told Us Weekly magazine.

“There was a ton of security because people were scrambling to get a look. One person even climbed up on someone’s roof. They had to put a huge sheet of plywood up to prevent people from seeing her." (C) Cover Media
