I still think Beyonce looks better than Rihanna. I think Jay-Z is making her look ugly. And i think she was singin that song to the gannacologis(spelling? haahhahahahahahha))

hold up i thought that due to Contrast Theory a good looking person's good looks are emphasised by her companion's ugliness

so your theory flopped

plus...rihanna is a sexy lil thing and beyonce lost her sparkle years ago
