Rihanna's Bachlorette Party For Katy Perry Was A Circus (PHOTOS)

Rihanna and Katy Perry were spotted on Saturday, at the MGM Grand Hotel/Casino in Las Vegas. The two good friends attended the KA stage show performed by Cirque du Soleil and were pictured with some of the cast members after the show.

Katy Perry is photographed out one night after fiance, Russell Brand, was arrested while he traveled through LAX airport with Perry. He is being charged with misdemeanor battery, after attacking the paparazzi, which he claims was to protect his fiance from photographed upskirt.

Rihanna recently surprised everyone, making an unexpected appearance last weekend at the 2010 MTV Video Music Awards, where she shared the stage with Eminem.
