In the dream I was among a large group of people and jayz and rihanna were also there walking around in the same vicinity. Jayz had a stern look on his face and he was trying to prevent people from getting too close to rihanna. Rihanna was relaxed and calm and was greeting people while sticking close to jayz, then I walked to the middle of the crowd to get a look at rihanna and rihanna stopped what she was doing and looked through the crowd right at me and we both smiled, in the dream it was as if we knew each other from somewhere.
