AceShowbiz - Jennifer Aniston is taking extreme lengths to banish her 'girl-next-door' image once and for all - she's set to strip, take drugs and indulge in a threesome in her next movie, according to reports.

The "Friends" star's latest film "The Switch", about an unmarried woman who uses artificial insemination to have a child, was branded a flop earlier this month, amid scathing reviews and disappointing box office takings.

But Aniston is firing back at critics by taking up a role in Judd Apatow's "Wanderlust" opposite Paul Rudd. The pair will play a married couple who become hippies, while Aniston's character smokes cannabis, strips off her clothes and embarks on affairs, including one same-sex romp scene.
