Jennifer Aniston gives off some serious sex appeal in the trailer for upcoming comedy We're the Millers.

The sexy star shows off her amazing 44-year-old body as stripper Rose O'Malley in the promo -- but that's not the only reason to check it out.

Aniston stars opposite her Horrible Bosses co-star Jason Sudeikis in the movie, which centers on David Burke (Sudeikis), a single guy hired by a drug smuggler (Ed Helms) to help him get a "smidge" of marijuana across the border from Mexico. Naturally, the "smidge" turns out to be "enough weed to kill Willie Nelson."

David enlists the help of neighbor Rose, along with Kenny, a "dork" that lives in his apartment building (Will Poulter) and "little gutter punk" Casey (Emma Roberts) to play his fake family on a vacation south of the border.

Things take a turn for the worse, of course, and an international drug dealer gets involved, taking the "family" hostage and prompting Rose to prove she's a stripper. And prove it she does.

"We're The Millers" opens in theaters August 9.
