The singer, who is set to marry comedian and actor Russell Brand, said she wanted Rihanna to go all the way.

"I want her to strip at my bachelorette party,” Perry told Chicago radio station Kiss 103.5 FM.

"(I want to see) the whole bit. She's hot. I love her. She's the coolest chick and I want all of her clothes."

Perry and Brand, who began dating last September, are expected to wed later this year.

Meanwhile, Perry is set to release her second album 'Teenage Dream' in August.
