Pop singer Katy Perry, who got married to comedian Russell Brand last month in India, now wants her best friend R&B singer Rihanna to walk down the aisle.



"Katy thinks I should get married now, but she needs to calm down on that one. I mean, one day, but not just yet -- we're having too much fun," stuff.co.nz quoted Rihanna as telling a magazine.

The Barbados-born pop star has been dating baseball player Matt Kemp, 26, since January and he had recently accompanied Rihanna on a trip to London.

And 22-year-old crooner admits that Kemp is her biggest critic.

"He's my number one critic. I played him my new album 'Loud' when it was done and in the most part he liked it, but we did argue about it too. He likes the ballads," she said.
