Rihanna is helping out Katy Perry with her Hen night.

The I Kissed A Girl singer is currently engaged to British comedian Russell Brand - and good friend Rihanna is said to be keen to make sure Perry only enters into married life after having some wild fun.

“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 More! magazine.

“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.”

Rihanna has previously said she thinks Katy Perry and Russell Brand are “hillarious” together.
