To say that Rihanna is unhappy with The Sun newspaper is an understatement. The British outlet reported that RiRi used a body double in her Armani ad closeups, and the 'Where Have You Been' singer lashed out -- where else? -- on Twitter.

A source told The Sun that a model named Jahnassa Aicken's bod appears in the commercial. “Jahnassa’s torso, body and bum appear in parts of the ad," the source revealed. However, Aicken allegedly signed a confidentiality agreement blocking her from talking about the gig.

That's with pretty good reason: the makers of the ad could be in deep doo-doo if in fact Rihanna's booty wasn't in those shots. An Advertising Standards Authority spokesman warned, “If we have complaints consumers have been misled by the use of a body double, we will investigate."

For her part, RiRi is P.O.ed. She sent The Sun a series of profane tweets as well as starting a global trending topic of "Who is Jahnassa." Per The Daily Mail, the Bajan beauty wrote, “Ok @thesunnewspaper, this is the only way I could say this to you!!! F--- YOU….AND yo baggy a-- condom.” Geez Rihanna, you kiss your mother with that mouth?
