It has been reported that singers, and former best friends, Katy Perry and Rihanna are still arguing about Rihanna's decision to let Chris Brown back into her life. It was claimed last November that Katy was angry with Rihanna for forgiving Chris for what he did to her and the two women are still not speaking.
Rihanna and Katy Perry both attended the Grammy Awards at the weekend and it is said that the two singers kept their distance, as their feud over Chris Brown continues. It seems that Katy simply cannot forget what Chris did to Rihanna and is not yet ready to let it go.
A close source to the pair was talking to Us Weekly, when they opened up about the whole situation, saying "They aren't tight anymore because Katy doesn't approve of Rihanna dating Chris Brown," despite the fact that Rihanna has openly accepted Chris back into her life.
Instead of spending any time with Rihanna at the Grammy Awards on Sunday, Katy Perry spent the majority of the evening with her boyfriend John Mayer and the couple enjoyed the event from the front row. Meanwhile, Rihanna spent some of her time with Chris Brown, sat somewhere else in the audience.
