Jennifer Aniston was America's sweetheart as the loveable Rachel Green on the hit 90s sitcom “Friends,” but that doesn't mean she doesn't have a mean streak.
“There’s a little nasty in everybody, whether they say it or not,” she told FOX411’s Pop Tarts column while promoting her new comedy, “Horrible Bosses.” “Everybody gets frustrated."
Aniston plays sexually twisted dentist Dr. Julia Harris in the flick, which opens in theaters this weekend. Aniston's character makes shocking, X-rated advances on her male dental assistant, and threatens to destroy his upcoming wedding.
“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,” she continued. “The part was irresistible.”
The role also features Aniston in just a lab coat and underwear, devouring a procession of phallic symbols in sexy lingerie, and talking dirty in a bathtub.
“It was fun, over way too fast. I loved her (Julia) and was sad to see her go,” Aniston said. “I loved her, I fell for her.”
It all seems to be working. As of Wednesday, “Horrible Bosses” had an impressive 83 percent rating on movie critique website Rotten Tomatoes, with critics commending it for its “nonstop laughs,” “whip-smart script,” and the “chemistry between its actors.”
But Aniston’s sexually inappropriate character has also ignited some controversy. In one scene, Dr. Harris calls her dental assistant a gay slur.
“You’re starting to sound like a little f****t there, Dale,” she says.
Gay slurs – even under the umbrella of comedy – don’t always sit well in Hollywood.
Last year, GLAAD (The Gay and Lesbian Alliance Against Defamation) demanded that Universal remove the trailer for Vince Vaughn’s comedy “The Dilemma” and edit out the a line calling electric cars “gay.” The organization’s outcry had Hollywood taking sides.
In the case of Aniston’s character, the writers of the film have defended the use of the term by saying that it was included to further illustrate just how “horrible” Aniston’s character truly is. “I think when it is coming out of her mouth, it is understandably offensive,” co-writer John Francis Daley told The Daily Beast.
GLAAD did not respond to FOX411's request for comment.
