Rihanna is back modeling for Armani and thankfully this ad campaign is way better than the first one shot by Steven Klein. This time around famed photographers, Mert & Marcus, photographed the Emporio Armani Underwear & Armani Jeans Spring 2012 ad campaigns featuring Rihanna, which took place in Dublin. These images are way simpler but still sexier and more fashionable than their 2011 campaign, have a look!
