She's not the Only Girl in that advert! Rihanna used an Irish model as a body double in Armani video
She's got a body that most women are enviable of, but it seems Rihanna isn't as confident as you'd think.
The 24-year-old is said to have used a body double for the sexy Armani advertisement which she filmed earlier this year.
However, Rihanna may not be so forthcoming about this revelation and no doubt wants fans to believe she features throughout the minute-long video.

Not so confident: The other woman's body is said to belong to Irish model Jahnassa Aicken
According to The Sun, Irish model Jahnassa Aicken is the other woman who bares her body in a pair of designer knickers.
However, Rihanna's management allegedly made her sign an order banning her from speaking about the fact that she was used as a double.
'Jahnassa's torso, body and bum appear in parts of the ad,' a source told the newspaper.

Whose bottom is it?
The advert shows a female pulling on a pair of Armani jeans while wearing lace underwear but it may not be Rihanna
'It's shocking Rihanna wanted one considering she loves posing with no clothes, plus she's in great shape.'
The advert shows Rihanna laying in a large double bed on her own wearing black lace underwear as she appears to have a nightmare.
It then cuts to her getting out of bed as she picks up the telephone and Aoficken then slips into a pair of Armani jeans and a leather jacket.
The close-up shots of the singer's derriére and of her bust are said to be Jahnassa - not Rihanna.

The Umbrella singer - who first stated that she would be collaborating with Armani late last year - clearly wasn't feeling over-confident about her own figure.
Jahnassa - who is signed to Style Academy Model Agency - is said to have received a 'modest sum' for the job, and was first spotted by Rihanna's people in a crowd during the filming of her We Found Love music video in Northern Ireland.
'If we have complaints consumers have been misled by the use of a body double, we will investigate,' an Advertising Standards Authority spokesman told the newspaper.
