Singers Rihanna and Katy Perry were living like true rock stars this weekend in Las Vegas. The duo partied with 25 people as Perry is preparing for her marriage to British comedian Russell Brand.

They went to the MGM Grand hotel to see a Cirque du Soleil production, after which they went backstage to pose pictures with the colorfully dressed cast. They finally ended up at a strip club (Location Unknown), where a blonde stripper danced for bride-to-be Perry.
