Have Katy Perry and Rihanna fallen out over Chris Brown?

It’s starting to seem that way, as the two pop stars haven’t been seen out together since the MTV Video Music Awards and Katy told MTV recently that she “didn’t reach out to her after that incident.” Hang on! What incident? It’s hard to tell exactly what Katy’s talking about here but we reckon that she could be talking about Rihanna and Chris Brown’s very public kiss, which took place at those awards, where they were last seen hanging out.

The kiss was met with widespread disbelief and condemnation (as Chris Brown was convicted of assaulting Rihanna when they were dating back in 2009) and now it looks as though Katy Perry is joining the growing group of people to speak out about Rhi-Rhi and Chris Brown rekindling their relationship. Katy was careful what she said about Rihanna though, so as not to completely destroy their friendship. “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 wants a break.”

Previously, Katy and Rihanna could be frequently spotted out and about showing their love for each other and often communicated their mutual respect via Twitter. Could this be the end of a very beautiful friendship? It certainly sounds as though Katy’s giving Rihanna a wide berth right now. But will she be there to pick up the pieces if things go wrong with Chris Brown again? 

It was a brief kiss, but is THIS what's caused a rift between Rihanna and Katy?
