Rihanna's reunion with Chris Brown has hurt her friendship with Katy Perry.
Perry, who got close with the "Stay" singer at last year's Grammys, "doesn't approve" of Rihanna's decision to get back together with Brown, 23, and their friendship has suffered as a result of it, sources told Us Weekly.
"They aren't tight anymore because Katy doesn't approve of Rihanna dating Chris Brown," an insider told Us.
I think there are only two people who really think this whole Chris Brown/Rihanna thing is a good idea.
Brown assaulted Rihanna on the eve of the 2009 Grammys and was eventually sentenced to community service for the attack. Los Angeles prosecutors are now investigating whether Brown faked his community service records.
Perry spent the evening of the Grammys on the arm of her man, John Mayer. The couple had a front-row view of the night's performances, while Rihanna and Brown cuddled up elsewhere in the audience.
Well, that settles it, then. They all obviously hate each other.
