EXCLUSIVE PHOTOS - Rihanna Heads To A Photo Shoot In A Skimpy Black Slip

We caught Rihanna arriving at a photo shoot on Saturday, and the 24-year-old singer kept it simple in a skintight black slip, glasses and high tops, but she still looked smokin' hot!

While she seemed a little bit sleepy when she hopped out of the car, she definitely perked up once she started shooting with pal Terry Richardson, and she later tweeted the photo below and wrote, "#dopedealersh*t @terryrichardsonstudio can't wait til you release your exclusive sh*t!!! Can't wait to do it again, you ph*cking rule bro."



Hawt!
