Raunchy Rihanna has shown off her wild side yet again by stripping down to her underwear in the back of a limousine for a new advertisement.
The Umbrella hitmaker signed up to star in a new ad campaign for Armani Jeans, and she leaped at the chance to show off her famous curves.

In the black and white promo, posted online on Thursday, the singer is seen sporting a blonde wig as she sits on the back seat of a stretch limo in an underground car park, where she is given a sports bag by a mystery hunk.

She then slips out of her designer dress and wriggles into a pair of skin-tight jeans and a figure-hugging leather jacket before joining the man in an elevator and flashing a mischievous grin.

Last month, Rihanna’s notorious saucy antics landed her in hot water when she was ordered to cover up by a local farmer while shooting a music promo in a field in Bangor, Northern Ireland.
