The former 'Friends' star, who is famous for her 'girl-next-door' image, suffered box office disappointment recently after her new film 'The Switch' bombed at the US charts. It follows other under-performing films like 'Love Happens' and 'The Bounty Hunter'.
However, in what appears to be a bid to reinvent herself, Aniston will strip off on screen for the first time in her acting career in 'Wanderlust'.
Directed by 'Knocked Up's Judd Apatow, the film will see Aniston play a 'free loving' married woman who lives in a hippie commune. Her character will reportedly take drugs and sleep with men and women.
Apatow regular Paul Rudd will play Aniston's husband in the movie. Aniston and Rudd last appeared on screen together in the quirky 1998 romantic drama 'The Object of My Affection'.
'The Switch' will be released in UK cinemas on 1 September.
