According to the New York post, Rihanna's recent reunion with Chris Brown has put a damper on things with her best pal Katy Perry.  Allegedly, the two girls are barely speaking.

Sources close to Katy say that there has been a lot of tension between the two.  They say Katy, like many others, fear that Rihanna is " making a huge mistake and doesn’t want to be part of it.”

Rihanna seems like the stubborn type.  It'd be pretty sad if she loses Katy as a friend over this.
