AceShowbiz - Katy Perry is determined to have a stripper at her bachelorette party - and she is urging Rihanna to do the honors by baring all. The "I Kissed A Girl" hitmaker is preparing to marry British funnyman Russell Brand and she's given Rihanna the task of organizing a pre-wedding bash before she walks down the aisle.

Perry has decided she won't hire a professional exotic dancer for the event, because she wants Rihanna to show off her body in a sexy striptease. She tells U.S. DJ Nina Chantele, "(Rihanna) has all these ideas about everything. You see people coming and they strip at your bachelor party but I want her to strip at my bachelorette party."

"She's going to get the message right now. She's hot, I love her. She's just the coolest chick and I want all of her clothes. We have a lot in common. We like to hang out every once in awhile, sometimes we'll see each other at different events."

"I don't know if she started this rumor that she's going to do it or if she just hopped on the bandwagon of the rumors like, 'I'm going to do it!' That's the one thing that I don't have to plan, which I'm really excited about."
