Overseers of Abu Dhabi's Grand Mosque said Monday, Oct. 21, 2013 they asked pop star Rihanna to leave the compound after she posed for photographs considered to be at odds with the "sanctity" of the site. Photos posted on various websites show the singer posing on white marble, dressed fully in black, with her hair covered according to the mosque's guidelines. Earlier, Thai authorities arrested a bar owner in connection with a lewd sex show mentioned in racy tweets by pop star Rihanna during her recent trip to Thailand, officials said Monday, Oct. 14, 2013, two weeks after an Instagram photo of her with a protected primate led to the arrest of other two men.
