Katy Perry has no idea how is best friend Rihanna

According to reports, Perry fell out with Rihanna after she got back with rapper ex-boyfriend Chris Brown, reported Sun Online. When asked about whether she's seen Rihanna recently, Perry said, "We've had dinner, and that's about it, I didn't reach out to her after the incident.

I think she is doing fine. "I don't know. Her personal life has probably already been blown out of proportion. I don't really have to go into that. I'm sure she probably want's a break," Perry said. They were last seen together at the VMAs, getting along well, until Rihanna was pictured kissing Brown in the audience.
