When asked how much she wants Rihanna to show, Katy replied: "The whole bit, the whole bit.
"She's gonna get the message – she's hot I love her and she's the coolest chick and I want all of her curves and we have a lot in common."
Katy admits that RiRi is such a great pal she offered to plan the bachelorette party without Katy having to ask. Katy recently said, "That's the one thing I don't have to plan and I'm really excited about it."
Oh to be a fly on that wall. Can you imagine partying hard with Katy and Rihanna during a naughty bachelorette party?! Take lots of pictures ladies!
