Rihanna: Katy Perry’s Bachelorette Party in Vegas!

Rihanna treats her BFF Katy Perry (in Dolce & Gabbana paired with Jimmy Choo shoes) to the gravity-defying production of “Ka” by Cirque du Soleil at the MGM Grand Hotel/Casino on Saturday (September 18) in Las Vegas, Nevada.

The twosome went backstage after the show and met all of the performers. Looks like a blast — good choice, Ri!!!

The party continued afterward as Katy tweeted, “Signing up for a liver transplant now…” She will soon tie the knot with British comedian Russell Brand.

FYI: Ri has already been spotted back in Cali. She dined at Il Ristorante di Giorgio Baldi in Santa Monica with friends!
