The Friends alum was very nonchalant as she dropped the first expletive on the show, in response to a query from O'Brien about her jewelry choices for the role.
"Oh that's a c*ck ring," she replied, explaining the necklace choice her character Dr Julia Harris, a sex-crazed dentist, was wearing in the promo shot O'Brien had shown.

Mock-surprised at the audience's shocked response she continued, "It is a c*ck ring."
"Was that your acting choice?" a perplexed O'Brien asked.

"It was an active choice," Aniston, who was dressed in a pretty strapless gray dress, replied. "It was one of those things where they lay out the jewelry, and I gravitated towards that beautiful piece of jewelry," she explained.
"I put it on and I was like, 'This is unique and cool.' And I kept on trying on other bits of her wardrobe and I just kept it," Justin Theroux's finace added.
"They said 'Great, you chose the c*ck ring'. And I was like, 'I'm sorry, come again?'"
At this point Aniston decided there was no point at all trying to keep her language in check.
