She covers her modesty with a digital cartoon octopus pastie.
In the next photo where she's freshly bathed, the former fiancee of Liam Hemsworth is seen in a bikini.

Lena Dunham and Suki Waterhouse have joined the fight as well.
Rihanna, meanwhile, has her Instagram account shut down for violating the community guidelines after posting a nearly nude picture.
