A poster of R&B star Rihanna advertising her perfume has been restricted by the advertising watchdog to areas where children are unlikely to see it.

The Advertising Standards Authority (ASA) found the image of the singer "sexually suggestive". It shows Rihanna, apparently naked, sitting on the floor with her legs raised against a bottle of Rogue scent, reported BBC online.

Parlux Fragrances said that the nudity was not improper and the image was not offensive, suggestive or demeaning. The ASA accepted Rihanna was mainly covered and had a facial expression "of defiance rather than vulnerability".

"While we did not consider the image to be overtly sexual, we considered that Rihanna's pose, with her legs raised in the air, was provocative.

"Because of this, and the fact that Rihanna appeared to be naked except for high heels, we concluded that the ad was sexually suggestive and should have been given a placement restriction to reduce the possibility of it being seen by children," it said.
