Jennifer Aniston welcomed the chance to get down, dirty and just plain nasty for her role in Horrible Bosses as a manic and seductive dentist whose favorite past time is sexually harassing her assistant (Charlie Day).  So when did Rachel Greene (Jen circa Friends days) become so naughty?

As Dr. Julia Harris in the hotly-anticipated comedy, Jen's character threatens to destroy her assistant's (Charlie) upcoming wedding with her sexual advances and X-Rated pictures.

“I loved the script, I thought it was extremely unique idea that everybody universally would be able to relate to, in terms of having a boss that’s a little difficult,” Jen said. “The part was irresistible.”

She continued: “It was fun, over way too fast. I loved her (Julia) and was sad to see her go. I loved her, I fell for her.”
