From the looks of these photos the much anticipated “craziness” (i.e. rumors of Rihanna stripping at Katy Perry’s bachelorette party) didn’t happen in Vegas this weekend. Rihanna helped her BFF Katy Perry celebrate her upcoming nuptials by partying with Perry in Las Vegas. The ladies hung out at the pool, got a table at XS Nightclub and even hung out with the Cirque Du Soleil cast backstage. Does Rihanna have any black celebrity girlfriends?
