Rihanna’s black-and-white photo shoot is her second for the Italian brand. Her previous, also in black-and-white, saw her strip down and don a short blond wig. She’s more natural in the latest photo series. Her hair is straight, dark and just past her shoulders.

Rihanna redefines sexuality in her newest campaign photos for Emporio Armani Jeans, and she even keeps most of her clothes on! No wonder her ads were voted the sexiest for 2011.

In a poll of advertising industry executives by trade publication Advertising Age, the Bajan singer’s first Armani campaign received top honors. “It’s Rihanna at her sexiest,” the magazine editors proclaimed. “She’s never looked this good [and] she’s in amazing shape and the pictures are stunning.”

Model Miranda Kerr finished in second based on her campaigns for Victoria’s Secret. She was back in a bikini just weeks after having her first child last year. British supermodel Kate Moss, who just turned 38, finished third. She was cited for her topless campaign for Italian clothing brand Liu Jo.

Rihanna: Improper Entertainer of Year

In her latest campaign, Rihanna is featured in a white tee-shirt tied around her midriff with her sleeves rolled up. She’s sprawled seductively on a couch. In another photo she stares into the camera wearing high-waisted shorts and a jean jacket braless. Two other shots show her in lingerie.

Rihanna just finished a brutal European tour where she was forced to cancel several shows because of exhaustion. The singer was put on a health watch to finish the tour because part of her problem involved extensive partying.
