VladTV: Just one year ago at the Grammy awards Katy Perry and Rihanna couldn't help gushing over their close friendship, but this year was a different story. No photos emerged of the two hugging or talking at the awards show, where they were seated away from each other.
Sources in the know told US Weekly that Katy strongly disapproves of Rihanna's relationship with Chris Brown and thinks she's making a huge mistake by giving him a second chance.
Back in November it was reported that Katy and Rihanna were barely speaking over her decision to start dating Chris again. At the time, a source close to Katy revealed that tension was brewing between the two close friends, and noted that Rihanna was noticeably absent from Katy's annual Halloween party.
The two BFFs haven't been seen out in public since September at the MTV Video Music Awards, where Rihanna planted a kiss on Chris Brown.
