| by Oh The Scandal

Rihanna threw a bachelorette bash for BFF Katy Perry in Sin City over the weekend.

Perry was joined by 25 of her closest friends in Las Vegas, reports

 The party began pool-side at the Hard Rock Hotel & Casino’s “Beach Club,” while Perry tweeted, “Signing up for a liver transplant now…”

The gang then took in a performance of KA by Cirque du Soleil at the MGM Grand Hotel and posed backstage with cast members.

The party reportedly ended up at Sapphire strip club, where the ladies ducked into the VIP area for more fun, frivolity and, as People put it, “inflatable objects consistent with bachelorette parties.”
