RiRi and Katy, real BFFs

"She's unbelievable, unbelievable! She is such a strong being. She wants to be there for me and I'm like, ‘Girl, I'm supposed to be there for you, don't worry about me right now!' She's incredible like that. She's one of my best friends in the industry," themirror.co.uk quoted Rihanna as saying.

"When I came into this industry, I just identified with Katy and not a lot of women I meet I can click with and right away. And I just knew I loved her honesty, it was pure and it was fresh. And I enjoyed her company."
