When Rihanna isn't on vacation— ya'know, chilling out, smoking weed and stuff— she's a pretty big pop star and also the face of Emporio Armani Underwear and Armani Jeans. She's even got her own Armani  fashion line. These new shots are presumably for Armani Jeans, though. Nice, right? She appears to be topless under that denim jacket. Doesn't get much hotter than that.
