Katy Perry is keeping her distance from Rihanna.
According to Us Weekly, the former best friends have fallen out over Rihanna’s relationship with Chris Brown.
“They aren’t tight anymore because Katy doesn’t approve of Rihanna dating Chris,” an insider told the magazine.
Rihanna sat next to Brown at this year’s Grammy Awards — a big change from previous years, when she and Perry sat together.
Meanwhile, Perry was spotted in a different section of the audience, launching speculation that she had requested to sit away from Brown and Rihanna. Published reprots have speculated that tension has been brewing between the two pop stars since November.
