Katy Perry has heaped the pressure on best pal Rihanna after asking her celebrity best mate to organize her bachelorette party.
Rihanna was in the throes of announcing her summer tour with Ke$ha when Perry dropped the bombshell and gave her pal the task of coming up with a wild bash to celebrate her upcoming wedding to British funnyman Russell Brand.
The R&B star says, "She put that on me last week and now I have to come up with something cool 'cos she's getting married in India, so I'm like, 'OK and now what do I do to match that for a bachelorette party?'"
But she has a bit of planning time: "That's at the end of the year, so we've got some time to plan that."
