Rihanna's latest ads for Emporio Armani Underwear and Armani Jeans' Spring/Summer 2012 ad campaign have hit the web, and the 23-year-old R&B star looks hot hot hot! RiRi posed for shutterbugs Mert & Marcus Piggott in Dublin, Ireland, and it's pretty clear to see why Armani chose her as the face (and body!) of their brand.

Rihanna is currently vacationing in Hawaii, and the other day the starlet tweeted, "Kush rolled, glass full...I prefer the better things!" Interestingly enough, photos surfaced of the starlet puffing on a suspicious-looking cigarette after a workout, so it looks like she really is enjoying the island lifestyle!
