Pop superstar Rihanna has courted controversy once again by sharing snaps of herself completely naked. The Umbrella hitmaker posted two photos on Instagram.com on Monday (21Oct13) showing her sitting naked in a bathtub, blowing bubbles and preserving her modesty with only her bare legs. The raunchy images, which were taken in Greece, were published just days after the star was asked to leave the Sheikh Zayed Grand Mosque in Abu Dhabi for posing seductively outside the building while wearing a figure-hugging black jumpsuit and a head scarf. Officials at the religious building were angry because she refused to ask permission to use the location for the shoot on Saturday (19Oct13). Rihanna is currently travelling for her Diamonds World Tour and is due to hit the stage in Tel Aviv, Israel, on Tuesday (22Oct13).
