Her lingerie advertising campaign for Armani was voted the sexiest set of 2011, and Rihanna didn’t disappoint when she posed for the brand once again in January.

But while the singer offered saucy snaps in her print campaign, it is a new video for Armani jeans in which Rihanna really sets pulses racing.

The 24-year-old pushes her sex appeal to the maximum as she can be seen acting out a bad dream while she writhes around in her underwear.

It may be hard to tell it is the designer’s denim line that Rihanna is promoting as she spends most of the advert in just a bra and knickers.

But at the end of the black and white clip she slips a pair of jeans over her pert derriere.

Rihanna then forgoes a top but pulls on just a leather jacket as she grabs her bag and heads out the door before briefly checking out her reflection in the mirror.

Well damn Rihanna!! Damn!!
