Rihanna, who was named the face and body of the brand's underwear and jeans collection last summer, acts out a bad dream in the moody black and white video.

Previously, she also posed for photographs for the campaign in her underwear, which saw her win the 'Sexiest Advert of 2011' accolade by Advertising Age.

"It's Rihanna at her sexiest. She's never looked this good. She's in amazing shape and the pictures are stunning", the magazine commented.

23-year-old unveiled a clothing collection for the Italian fashion house last November.

Celebs like Megan Fox, David Beckham and Cristiano Ronaldo have also modeled for the Italian fashion house.
