(Cover) - EN Showbiz - Jennifer Aniston has joked it has always been her dream to play a sex-starved dentist.

The actress is best known for playing ditzy Rachel Green in US sitcom Friends, but is set to shock with her role in upcoming movie Horrible Bosses. In the film her character, Dr. Julia Harris, blackmails an employee to make him have sex with her.

Jennifer enjoyed getting into the role and welcomed the opportunity to play a different type of character.

"I have just played a pretty crazy person," Jennifer is quoted as saying. "I'm a dentist who's kind of sexually deviant. It was so much fun to play someone like that. In fact it was always my dream to put people under and have my way with them!"

The 41-year-old actress has previously confessed she was shocked by how easily she found it to use obscene language for the role. Jennifer was concerned she would stumble over the foul words her character uses, but admitted it had unlocked a darker side to her personality.

"The crazy part is the ease with which all these words are falling out of my mouth, Jennifer laughed.

Jason Bateman, Kevin Spacey, Colin Farrell, Jason Sudeikis, Jamie Foxx and Charlie Day also star in Horrible Bosses, which is due for release later this year. (C) Cover Media
