The 41-year-old actress uses lustful language for her role as a sex obsessed dentist who blackmails her colleague - portrayed by Charlie Day - to make him have sex with her in new movie `Horrible Bosses`.

But rather than shy away from the racy words Jennifer embraced the audible erotic challenge.

She said: "The crazy part is the ease with which all these words are falling out of my mouth. I don`t know what I`ve unlocked here."

The screen beauty also had to strip off for the role and she admits she was nervous about ditching her clothes in front of Charlie.

She added to the USA Today newspaper: "It`s so funny and weird and twisted. I`m naked with Charlie Day, who I`ve known for minutes."

Jennifer also claims she can relate to her character Kassie in upcoming movie `The Switch`, a single woman who uses a sperm donor to get pregnant.

She said: "Kassie is your universal New York City girl, and she`s got a job and is living her life. I grew up in New York City, am currently single, not in search of a donor, but have a lot of sympathy and consciousness around this question because a lot of my girlfriends have dealt with it. What does Mr. Right mean? I love the debate. It`s awesome."
