Before the evening festivities, Rihanna and Katy Perry hung at the pool in the Hard Rock Hotel Casino for a day of sun and fun to celebrate Katy's Bachelorette Party on September 18, 2010. Katy sipped on Bud Light Beers and smoked cigarettes with friends and everyone was having a great time and laughing together almost constantly. Rihanna was wearing a long red colored wig and large gold hoop earrings. She and some friends looked through pictures on a camera and had a huge laugh as well.
