Rihanna opens up on hen do planning for Katy Perry

The Umbrella songstress has revealed she's feeling the pressures as she plans Ms Perry's big bash

It's set to be the Hollywood wedding of the year, so no wonder Rihanna has revealed she's feeling a tad under pressure planning Katy Perry's hen party.

The Umbrella songstress opened up to Access Hollywood on the impending big bash and explained: 'It's taking up way more time than my tour! 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.'

But with Katy there, Rihanna added that it couldn't help but be a wild night: '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.'

Although there's been no word as yet from Perry's camp as to when she will wed Russell Brand, Rihanna has previously hinted that the big day will be at the end of 2010.

Speaking to Ryan Seacrest on a US radio station in April, Rihanna revealed that the couple were to marry at the end of the year in India, which is where Russell proposed last December.

The revelation came as Rihanna described how Katy has put her in charge of planning the party. She told Seacrest: 'She put that on me last week, I have to come up with something cool because she's getting married in India so I'm like 'Okay, 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,' she added.
