Katy Perry says that she is not supportive of Rihanna's relationship with Chris Brown.  This is a complete 180 from last years Grammy Awards when Rihanna and Katy Perry were tight the entire evening.  However, the pop sensations kept their distance at this years awards ceremony and kept close to their men.  Katy Perry was seen with John Mayer while Rihanna cuddled with Chris Brown.
