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."
