Popstar Rihanna is not only queen of the charts - she's also the queen of effortlessly cool street style! Whenever Rihanna is caught out and about, she always looks edgy, cool, trendy, and fashionable. And she is always switching up her hair (fire engine red to bleached blonde) and personal style, whether she's going for a glam, rock chick, or feminine look. Check out some of my favorite snapshots of Rihanna's street style in the gallery.
