Maybe just to look at. But voice and sex appeal also matter. Beyonce suffers there. Her voice is unbearable IMO. It has a very deep masculine tone. Also she lacks natural sex appeal. She simply doesn't exude the effortless sexiness of a girl like Rihanna.
The baddest bytch of all-time is Marilyn Monroe. She had it all. The look. The sweet feminine voice. And natural sex appeal.
