"It's taking up way more time than my tour," she said. "It's so much pressure. Her wedding is probably going to be the best wedding I've ever been to and now I have to match the bachelorette party to that ... I could have balloons and Disney characters there and she'll still make it wild. That's just Katy Perry. There's no way around that with her."
Katy does have one wild idea - she wants Rihanna to be the stripper.
"You see people coming and they strip at your bachelor party," Perry said. "But I want her to strip at my bachelorette party."
Katy said she wanted to see "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."
"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."
