Jennifer Aniston and Justin Theroux might not be heading down the aisle any time soon, but the pair demonstrates some chemistry in the trailer for their upcoming film, "Wanderlust."

The couple got close on the set of the R-rated comedy, which follows Aniston and Paul Rudd as they leave their city lives and land in a clothing-optional hippie commune.

In the trailer, Theroux is shown teaching Aniston to milk a goat, offering tips like "work the shaft" and "flick the tip." Meanwhile, Rudd's character is offered some free love from Malin Akerman.

"Wet Hot American Summer" director and co-writer David Wain directed and co-wrote the script with "Party Down" actor Ken Marino. The Apatow Productions and Universal Pictures flick is slated for release on February 24, 2012.

Aniston recently denied rumors that she was pregnant and engaged, explaining that she has gained weight because she quit smoking.

The 42-year-old actress made her comments to the tabloid Hello! magazine during a press conference to promote "Five," a Lifetime cable network film series about breast cancer that featured her as a first-time director, People reported.

"Rumor No. 1 - I am not planning to get married any time soon," the magazine quoted Aniston as saying. "I've been married once, and I don't know if I'll get married again. But I can tell you that as of this very moment, I have no plan to get married. Got that? And rumor No. 2 - no, we're not pregnant. It's just I quit smoking, so I've gained a couple of pounds."

Aniston has been dating Theroux, a 40-year-old actor, since at least this past May. She was famously married to Brad Pitt between 2000 and 2005. Aniston fueled engagement rumors several months ago when she was photographed wearing a sparkly ring.

"Wanderlust" is slated for release on February 24, 2012. Watch a trailer below.
