Rihanna organising Katy Perry's hens' night

Rihanna is rumoured to be planning a huge girls' night out for her gal pal Katy Perry before her upcoming wedding to Russell Brand.

"Katy's totally excited and keeps telling Russell her party is going to be every bit as wild as any party he and his boys will throw!" a source tells Perez Hilton. Rihanna and Katy shouldn't have much trouble out-partying teetotaller Russ.
"She and Rihanna have become very, very close. So Rihanna has offered to plan a girls' getaway and also help out with anything else Katy needs for the wedding," adds the source.

How sweet. Rihanna would make a super hot bridesmaid too!
