It appears people never get tired of hearing Rihanna, reading about Rihanna or seeing Rihanna. Or maybe it's just us. Whatever. These are some pictures from her performance Radio 1's Hackney Weekend, where she joined Jay-Z on stage for "Run This Town," on Saturday. The next day, she took top billing at the event. We were kinda digging the high-waisted shorts here though. Of course, it could be because she's wearing little else.
