RIHANNA IS PLANNING KATY PERRY'S BACHELORETTE PARTY!

Rihanna and Katy Perry have been friends for a while now, so when Perry needed someone to throw her bachelorette party, she called on her fellow superstar pal. According to Rihanna, she's planning a blowout before Perry's wedding to Russell Brand.

"She put that on me last week," Rihanna told Ryan Seacrest on his radio show Friday (April 9), revealing another key detail about the forthcoming nuptials. "I have to come up with something cool, because she's getting married in India. So I'm like, 'OK, now what do I do to match that?' That's at the end of the year, so we've got some time to plan that."

Recently, Perry told MTV News that Brand has been a little too involved in planning their wedding details. "He's a total bridezilla. He's like a freak, man," she said at the Kids' Choice Awards. "You should see — he's always, like, buying bride magazines. Every time we go out for breakfast he's like, 'Can we just stop and get a bride magazine?' "

On Friday, Rihanna also decided to dish about her own love life, confirming to Seacrest that L.A. Dodger Matt Kemp is, in fact, her boyfriend. "He's my boyfriend," the singer said. "It's new and it's fun and it's nothing too serious. I don't want anything that's going to take up so much of my energy and time right now in a bad way. I just want to have fun, and that's what it's about."
