KATY PERRY SAYS SHE WANTS RIHANNA TO STRIP AT HER BACHELORETTE PARTY!

Katy Perry and Rihanna have been palling around since last year - but now Perry hopes the two will become even closer.

The "California Girls" singer says she wants RiRi to strip for her at her upcoming bachelorette party.

"You see people coming and they strip at your bachelor party," Perry said to Chicago's KISS-FM radio show, "but I want her to strip at my bachelorette party."

When asked how much she wanted to see of the Barbadian beauty during the dance, Perry responded, "The whole bit, the whole bit."

"She's hot, I love her. She's just the coolest chick and I want all of her clothes," Perry gushed.

Perry, who is engaged to funnyman Russell Brand, said Rihanna put herself in charge of organizing her bachelorette party without even being asked.

"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!,'" Perry said. "That's the one thing that I don't have to plan, which I'm really excited about."

The singers became friends last winter after Rihanna's Feb. 8 altercation with then-boyfriend Chris Brown. Since then, the two have been spotted everywhere together - vacationing in Barbados, dining in New York and hitting the red carpet.

"We have a lot in common," said Perry. "We like to hang out every once in a while."
