The 43-year-old revealed that her role in the upcoming comedy required her to be naked a lot of the time.
"Yeah, there was a lot of [nudity]," Aniston told ET Canada. "Bottomless, topless. Yeah, there is. It's happening."

She went on to say that being naked did not bother her in the slightest, adding: "'Liberating' is a good word to use."
Aniston recently insisted that being topless in Wanderlust was easy, claiming that stranger things had happened on set during filming.
The former Friends actress will receive a star on the Hollywood Walk of Fame in a ceremony later today (February 22).
Wanderlust is released on Friday (February 24) in the US and on March 2 in the UK.
