Jennifer Aniston ditches her 'girl next door' routine for a raunchier image in her very own 2009 calendar.

The Friends actress appears in a series of sexy shots, the majority of which have been pilfered from old magazine spreads.

And one photo in particular has been causing quite a stir because it leaves extremely little to the imagination.

In her most sexiest shoot to date - which is in fact a few years old - Jen shows off her gravity-defying breasts in a see-through wet T-shirt as she luxuriates under a waterfall.

The actress recently proved that she isn't all about sugar and spice and all things nice when she blasted her replacement in Brad Pitt's affections Angelina Jolie as "uncool" and labelled the press "motherf***ers".
