Irish model Jahnassa Aicken and Rihanna
Fans of Rihanna know all too well the Barbados beauty has no fear about stripping off in front of the cameras.

But they may be surprised to hear the 24-year-old is said to have used a body double for an Armani jeans advertisement she filmed earlier this year. The woman who stepped in in her place is none other than an Irish beauty of equal measure.

According to The Sun, Irish model Jahnassa Aicken also stars in the Armani ad dressed in a pair of designer underwear. But the sexy brunette was sworn to secrecy from speaking about her work as Rihanna’s double.

“Jahnassa’s torso, body and bum appear in parts of the ad,” a source told the newspaper.

“It’s shocking Rihanna wanted one considering she loves posing with no clothes, plus she’s in great shape.”

The ads shows Rihanna dressed in black lace underwear lying in a large double bed on her own. Seemingly distressed by a nightmare, the shot then cuts to her jumping out of bed before as she slips into a pair of Armani jeans and a leather jacket.

Some of the close up shots are said to be the Irish model who is signed to Style Academy Model Agency.

According to the newspaper Aicken was first spotted by Rihanna’s management when she
appeared in the star’s ‘We Found Love’ music video, which was shot in Northern Ireland.
