Katy Perry and Rihanna were best buds, but their friendship isn't doing too well these days and Chris Brown may be to blame.
According to the New York Daily News, Rihanna's relationship with Chris Brown has put a strain on her friendship with the "Part of Me" singer, and the two are "barely talking."
Sources close to Perry revealed "there has been tension" between the pop stars since Rihanna reunited with Brown, and she even skipped out on Perry's recent Halloween party. According to the source, Perry, like many others, fear that Rihanna is " making a huge mistake and doesn’t want to be part of it.”
