Although singer Rihanna physically looks great in this tight blue dress, she does not look all that happy. She does manage to show off her great legs and firm backside in this form-fitting dress, but it looks like her mind is elsewhere. One can only guess what might be weighing on her mind these days. These photos were snapped after the singer grabbed a snack in downtown New York. Rihanna manages to crack a few polite smiles, but she’s got some heavy thinking going on up there. Nice high heels, though.
