Most runway models aren't even beautiful. Rihanna >
Beauty is subjective, everyone has different taste. But out of the other girls Rihanna is the only one that has striking features and an overall aura that would make her a good runway or editorial model.
Hell no. She's decent looking with the right make-up & hairstyle(covering that forehead). She simply doesn't have a stunning facial bone structure like Beyonce or Halle Berry. Who can slay without make-up.
