Jennifer Aniston promises "a lot of penises" and "breasticles" in Wanderlust.

The actress stars as a woman who decides to quit her life and head to a nudist colony in the new romantic comedy, and assured viewers will get to see plenty of naked shots of her and her co-stars.

She told talk show host Chelsea Handler: "There's a lot of penises in this movie! Finally, for once, the men have to disrobe!

"Trust me, there is your fair share of breasticles as well. Penises are promised."

Chelsea also remarked to Jennifer: "I've been lucky enough to see you topless in our private life, but now America, when they go to see the movie, will get to see her topless running!"

The 43-year-old star replied: "There's a lot of nudity. And a lot of slow motion action nudity!"

Jennifer—who is dating Justin Theroux, who also appears in the film—has previously admitted she was nervous when she prepared for her nude scenes, but quickly adapted when it came to it.

She said: "There was a little bit of nerves, but adrenaline takes you through it. And then, you have the girls come in and cover you up, immediately.

"But I got very comfortable with seeing nude people, pretty much immediately. Shockingly, it was bizarre how at ease we became with having a bunch of naked people everywhere."
