Chris separates pals Katy and Rihanna

Katy Perry and Rihanna, who were once thick friends, are not speaking to each other. Katy is avoiding Rihanna because she has reunited with rapper Chris Brown. Perry reportedly made a special request to be seated nowhere near the couple at the Grammy Awards Sunday.

‘They aren’t tight anymore because Katy doesn’t approve of Rihanna dating Chris Brown,’ a source told usmagazine.com.

But friends close to Rihanna insist she has no problem with Perry, but doesn’t care what anyone thinks about her relationship. ‘Rihanna doesn’t have a problem with anyone and could give a f**k about what anybody thinks about her relationship. She was focused on her and Chris and enjoying her night,’ said another source.
