Jennifer Aniston may be 44, but that's not stopping her from taking her clothes off on the big screen!

Jen reunites with Horrible Bosses co-star Jason Sudeikis in We're the Millers, and she doesn't play a crazy dentist, but she does play a cynical stripper!

Jen rocks several wigs in the clip, and she performs strip teases in the club ... and for a drug lord with an automatic weapon. Ed Helms, Emma Roberts and Nick Offerman also star in the film ... check out the trailer below!
