Rihanna Uses Body Double for Armani Ad?

Photo by Lester Cohen/WireImageRihanna isn't taking kindly to a recent report from British newspaper The Sun that accuses the singer of using a body double in a sexy Armani ad that was released back in March.  Responding to the gossip, Rih tweeted the newspaper on Monday, writing, "Ok @thesunnewspaper, this is the only way I could say this to you!!! F**K YOU....AND yo baggy ass condom."

In the ad, a lingerie-clad Rihanna tosses and turns in bed, with the camera moving in on what's presumed to be her torso.  But according to The Sun, the butt that viewers gawked at belongs not to Rihanna but to Irish model Jahnassa Aicken.  The newspaper adds that Aicken signed an agreement banning her from talking about the matter, but Rihanna's apparently never even heard of Aicken.  "Who is Jahnassa," Rihanna tweeted, later adding, "Does she have a tat on her hand too."

There's no official word on whether all the body parts in the Armani clip belong to Rihanna, but an Advertising Standards Authority spokesman tells The Sun, "If we have complaints consumers have been misled by the use of a body double, we will investigate."
